Pakumanga kwamasiku ano, uinjiniya wamatauni, komanso minda yambiri yamafakitale, mapaipi a PVC amagwira ntchito yofunika kwambiri. Kugwiritsiridwa ntchito kwawo kwakukulu kumapindula ndi ntchito yawo yabwino komanso njira yopangira okhwima. Ndiye, njira yopangira mapaipi a PVC ndi chiyani kwenikweni?
Mapaipi a PVC amapangidwa kudzera mu njira yotulutsira zida za PVC ndipo nthawi zambiri amatsatira njira zomwe zimagwiritsidwa ntchito popanga chitoliro chokhazikika: Choyamba, ma pellets kapena ufa amadyetsedwa muPVC amapasa screw extruder. Kenako, kusungunula ndi Kutentha kumachitika m'magawo angapo a extruder. Njirayi ikuwoneka yophweka pamtunda, koma kwenikweni, imaphatikizapo matekinoloje ovuta komanso maulalo a ndondomeko, komanso mndandanda wa zida zamakono ndi mizere yopangira, pakati pawo pali ena oimira makampani opanga pulasitiki ku China.
Pa mzere kupanga mapaipi PVC, ndi extruder mosakayikira zida pachimake. Extruder imagwira ntchito yofunika kwambiri yosintha zinthu kukhala mapaipi opangidwa panthawi yonseyi. Kutengera chitsanzo chamakampani aku China opangira pulasitiki, mabizinesi ambiri akhala akufufuza komanso kupanga zatsopano pantchito iyi. Mwachitsanzo, Blesson, katswiri wodziwika bwino wa ku China wopanga zida zopangira zida zamagetsi, ali ndi chidziwitso chochuluka komanso wachita bwino kwambiri pa kafukufuku, chitukuko, ndi kupanga zida zotulutsa.Blesson's extruder makinafakitale utenga umisiri patsogolo ndi ndondomeko, ndi extruders opangidwa ndi ubwino waukulu mwa mawu mwatsatanetsatane, bata, ndi dzuwa kupanga, kupereka chitsimikizo olimba kwa kupanga apamwamba a mapaipi PVC.
Pamene PVC amapasa wononga extruder ndi ntchito, wononga kapangidwe ake ndi mwaluso anakonza. Zomangira ziwirizi zimagwirira ntchito limodzi kuti zida zopangira zizitha kuyenda molingana pansi pa kukankhira zomangira ndikumaliza kutenthetsa ndi kusungunula pang'onopang'ono m'magawo angapo. M'dera loyamba, zopangira nthawi zambiri zimatenthedwa kale kuti ma pellets kapena ufa ayambe kufewetsa, zomwe zimathandizira kukonza kotsatira. Pamene zopangira zimaperekedwa ndi zomangira kugawo lachiwiri, kutentha kumakwera kwambiri. Panthawi imeneyi, PVC imayamba kusungunuka pang'onopang'ono ndikupanga kusungunuka ndi madzi enaake. Pochita izi, kutentha kwa extruder kumagwira ntchito yofunika kwambiri. Kuwongolera bwino kutentha kumatha kuonetsetsa kuti zida za PVC zimasungunuka pa kutentha koyenera, kupeŵa kukhudzidwa kwa mipope chifukwa cha kutentha kwambiri kapena kutsika. Mwachitsanzo, ngati kutentha kuli kwakukulu, kungayambitse kuwonongeka kwa PVC, zomwe zimabweretsa mavuto monga kusinthika ndi kuwonongeka kwa mapaipi; pamene kutentha kuli kochepa kwambiri, kusungunuka kudzakhala kosakwanira, ndipo zotsatira zopanga mapaipi zidzakhala zosauka, ndi zolakwika zomwe zingatheke monga malo osagwirizana ndi mkati mwa inhomogeneous.
Zida za PVC zikasungunuka mu extruder, zimalowa mu gawo lopanga. Panthawi imeneyi, kusungunuka kwa PVC kumatulutsidwa kudzera mu nkhungu inayake kuti apange mawonekedwe oyambirira a chitoliro. Mapangidwe ndi kupanga kwankhunguzimakhudza kwambiri khalidwe lomaliza la chitoliro cha PVC. Zoumba zapamwamba zimatha kutsimikizira kulondola kwa mawonekedwe, makulidwe a khoma, komanso kusalala kwa mapaipi. Monga katswiri wopanga ma extruder waku China, Blesson wayika ndalama zambiri pakufufuza ndi chitukukonkhungukapangidwe ndi kupanga, ndi zisamere pachakudya zomwe zimapanga zimatha kukwaniritsa zofunikira zopanga mapaipi a PVC amitundu yosiyanasiyana komanso mawonekedwe osiyanasiyana ogwiritsira ntchito.
Mipopeyo ikatulutsidwa, imayenera kuziziritsa komanso kukula. Izi nthawi zambiri zimatheka kudzera m'matangi amadzi ozizira kapena zida zoziziritsira mpweya. Madzi ozizira muthanki yamadzi oziziraadzachotsa kutentha kwa mapaipi, kuwapanga ozizira ndi kukula mofulumira. Kuwongolera liwiro lozizirira ndikofunikiranso. Ngati kuzizira kwachangu kuli kofulumira kwambiri, kungayambitse kupsinjika kwa mkati mu mapaipi, zomwe zimakhudza makina awo; pamene kuthamanga kwa kuziziritsa kuli kocheperako, kumachepetsa kupanga bwino ndipo kungapangitse kuti mapaipi awonongeke panthawi yozizira.
Kuphatikiza pa maulalo akuluakulu omwe ali pamwambapa, kupanga mapaipi a PVC kumaphatikizanso njira mongakuchotsa unitndikudula. The kukoka mbali unit ndi udindo kukoka mipope extruded patsogolo pa liwiro zonse kuonetsetsa kupitiriza ndi bata kupanga chitoliro. Liwiro lothamangitsa gawo likufunika kuti lifanane ndi liwiro la extrusion. Ngati liwiro la kukoka kuli mofulumira kwambiri, mapaipi adzatambasulidwa ndikukhala ochepa; pamene ngati liwiro ndi wodekha kwambiri, mipope adzakhala mulu, zimakhudza kupanga dzuwa. Chipangizo chodulira chimadula mapaipi kukhala zinthu zomalizidwa molingana ndi kutalika kwake. Ena kupanga mizere ndi mkulu digiri ya zochita zokha, ndondomeko kudula akhoza kukwaniritsa mkulu-mwatsatanetsatane atakhazikika-utali kudula, kuchepetsa zolakwa chifukwa ntchito pamanja.
Mu China pulasitiki chitoliro extrusion makampani, Chinese opanga pulasitiki extruder ngati Blesson nthawi zonse kulimbikitsa chitukuko cha makampani. Sikuti nthawi zonse akupanga ukadaulo wopanga zida komanso akuchita kafukufuku wozama pamapangidwe onse ndi kukhathamiritsa kwa mizere yopanga. Mwachitsanzo, kudzera mu kukhathamiritsa kogwirizana kwa extruder, extrusion kufa, kuzirala, kutulutsa unit, ndi cutter, kupanga bwino komanso mtundu wazinthu zonse.Mzere wopanga mapaipi a PVCzakonzedwa bwino. Pakalipano, ndi kusintha kosalekeza kwa kufunika kwa msika, opanga awa akufufuzanso mwakhama ndikupanga mitundu yatsopano ya ma extruders ndi mizere yopangira kuti akwaniritse miyezo yapamwamba yopangira komanso zofunikira zogwiritsira ntchito zovuta.
Kuchokera pa kusankha ndi kuchiza zipangizo zopangira kusungunuka ndi kutentha mu extruder, ndiyeno kupanga, kuzizira, kugwedeza, ndi kudula njira, kupanga mapaipi a PVC ndi njira yovuta komanso yovuta. Ulalo uliwonse umafunikira kuwongolera ndikuwongolera, ndipo cholakwika chilichonse chaching'ono chingakhudze mtundu wa chinthu chomaliza. Chifukwa cha khama la mabizinesi ambiri ndi akatswiri mu makampani China pulasitiki extrusion, makamaka atsogoleri makampani monga Blesson, kudzera mosalekeza luso luso ndi ndondomeko kusintha, China PVC chitoliro kupanga wapezanso mpikisano wamphamvu msika mayiko. Kaya pomanga makina opangira madzi ndi ngalande, ulimi wothirira, kapena m'mafakitale monga mphamvu zamagetsi ndi zamagetsi, mapaipi a PVC opangidwa ku China apambana kuzindikira kwakukulu ndi mtundu wawo wodalirika. Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, akukhulupirira kuti njira yopangira mapaipi a PVC ipitilira kukula ndikusintha, zomwe zikuthandizira kwambiri pakumanga kwapadziko lonse lapansi komanso chitukuko cha mafakitale.
Pankhani yachitetezo cha chilengedwe, ndikugogomezera kwambiri chitetezo cha chilengedwe mdera la anthu, mabizinesi opanga mapaipi a PVC amayang'ananso njira zobiriwira zobiriwira. Kumbali imodzi, posankha zinthu zopangira, pali chizolowezi chogwiritsa ntchito zida za PVC zoteteza chilengedwe ndikuchepetsa kugwiritsa ntchito zowonjezera zomwe zimawononga chilengedwe. Kumbali inayi, popanga, pakuwongolera zida ndi njira, kugwiritsa ntchito mphamvu ndi kutulutsa zinyalala kumachepetsedwa. Mwachitsanzo, ma extruder ena apamwamba amatengera ma motors opulumutsa mphamvu ndi makina otenthetsera, omwe amatha kuchepetsa kugwiritsa ntchito mphamvu panthawi yopanga. Pakadali pano, pazinyalala zomwe zimapangidwa panthawi yopanga, mabizinesi akufufuzanso njira zobwezeretsanso ndikukonzanso zinyalalazo kukhala zida zomwe zitha kugwiritsidwanso ntchito kuti azindikire kukonzanso kwazinthu.
Kuchokera pamalingaliro akukula kwamakampani, njira zopangira mapaipi a PVC zidzakula m'njira zanzeru, zodzichitira, kuchita bwino kwambiri, komanso kubiriwira m'tsogolo. Zida zopanga zanzeru zitha kudzizindikiritsa ndikudziwongolera, kupititsa patsogolo luso la kupanga komanso kukhazikika kwazinthu. Mizere yopangira makina idzachepetsa ntchito zamanja, kuchepetsa ndalama zogwirira ntchito, ndikuwongolera kulondola kwa kupanga. Njira zopangira zogwira mtima zidzafupikitsa nthawi yopanga ndikupititsa patsogolo mpikisano wamsika wamabizinesi. Lingaliro lopangira zobiriwira lidzayendetsa ntchito yonse yopanga, kupanga mapaipi a PVC kukhala okonda zachilengedwe komanso okhazikika.
Pomaliza, kupanga mapaipi a PVC ndi njira yovuta yomwe imaphatikizapo maphunziro angapo ndi matekinoloje. Kuyambira zopangira mpaka zinthu zomalizidwa, ulalo uliwonse umakhala ndi nzeru ndi kuyesetsa kwa mabizinesi ambiri ndi akatswiri pamakampani opanga chitoliro cha pulasitiki. Ku China, opanga ma extruder aku China omwe akuimiridwa ndi Blesson akupanga zatsopano komanso kutukuka pantchito imeneyi, zomwe sizimangolimbikitsa kupita patsogolo kwa njira yopanga chitoliro cha PVC ku China komanso kumathandizira kuti pakhale mphamvu zatsopano pamakampani apadziko lonse lapansi. Ndi chitukuko chosalekeza cha makampani, tili ndi chifukwa chokhulupirira kuti mapaipi a PVC apitiriza kugwira ntchito yofunikira pakumanga zomangamanga ndi mafakitale amtsogolo, ndipo adzapindula kwambiri pokhudzana ndi khalidwe, ntchito, ndi kuteteza chilengedwe.
