M'munda wamakono wamakono wa mafakitale, kupanga kwapolyethylene (pe) mapaipi amakhala ndi udindo wofunikira kwambiri. Kaya zili m'madzi amatawuni, maukonde osinthira mabizinesi, kapena mapipu osiyanasiyana azolowa m'magawo opanga, mapaipi amapezeka bwino kwambiri chifukwa cha ntchito zawo zabwino kwambiri. Ndiye, kodi mapaipi a polyethylene amapangidwa bwanji? Lero, tiyeni tisamale Pinda ya pulasitiki yopitilira limodzi kuti mufufuze zinsinsi zomwe zimayambitsa.
I. Kuyambitsa: Zinthu zapamwamba ndi zofunikiraPE pip
Pakati pa chitoliro cha zopaka za pering komanso kupanga zopangira mayala, kusungunuka, kusakaniza zinthu zopangira, ndikuwawuza mawonekedwe ake, kutsatiridwa ndikusunga mawonekedwewo panthawi yozizira. Njira izi ndizofunikira pakupanga mapaipi olimba a khoma, mapaipi am'mbali, komanso kukakamiza ndi zopangidwa ndi jakisoni wowumbidwa. Munjira yovutayi komanso yosalala iyi, mosakayikira amagwira ntchito yayikulu. Wogulitsa ali ngati mmisiri waluso kwambiri, pang'onopang'ono pokonza zida zoweta monga polyethylene amaliza mawonekedwe a mapaipi omwe amakwaniritsa zofunika.
Ku China, patatha zaka chitukuko, makampani ogulitsa pulasitiki otukuka abwera chifukwa chopanga chitoliro cha pulasitiki chitoliro cha pulasitiki. Opanga odziwika bwino aku China, monga Damulo, ali ndi ma extring awo komanso othandiziraPINE PANGANI ZOPHUNZITSA kugwiritsidwa ntchito kwambiri m'misika yapakhomo komanso yapadziko lonse lapansi. Mabizinesiwa samangokhala ndi matekinoloje otsogola komanso mosalekeza ndalama zofufuzira ndi chitukuko ndi kupanga zatsopano, kuyesetsa kupereka zida zamapulasitizi zokhala ndi mafilimu, okhazikika, komanso anzeru.
Ii. Njira Yosinthidwa ya PEPI PRIP
1. Gawo lokonzeka
Gawo loyamba mu chitoliro cha pee kupanga ndi kusankha mosamala ndikukonzekera kwa zinthu zophika. Polyethylene ulen ndiye chinthu chachikulu, ndipo mawonekedwe ake ndi magwiridwe ake amakhudza mwachindunji mapaipi omaliza. Malo apamwamba a polyethylene ali ndi bata wabwino, kukana kuphulika, ndi mphamvu zamakina. Pakadali pano, zida zosiyidwa zimayesedwa mwamphamvu kuonetsetsa kuti zizindikiro zawo zonse zimakwaniritsa zofunika zopanga.
2..
(1) Kutentha ndi kusungunuka
Chotupa cha Exprider ndi gawo lalikulu kwambiri pamtundu wonsewo komanso kusungunuka. Zida zopangira zikalowe mu mbiya zam'matamboli, screw imayamba kuzungulira pansi pagalimoto. Kunja kwa mbiya kumakhala ndi dongosolo lotentha lomwe limawongolera kutentha mkati mwa mbiya. Pamene screw imazungulira, zida zopangira zimapitirira patsogolo mkati mwa mbiya. Pakadali pano, mothandizidwa ndi gulu lankhondo lamphamvu ndi kukangana kwakukulu, pang'onopang'ono amatenthedwa ndikusungunuka ndikusungunuka. Njirayi imafuna kuwombera ndi liwiro lokhazikika kuti muwonetsetse kuti zinthu zopangira zitha kusungunuka kwathunthu ndipo mtundu wa kusungunuka ndiwofanana.
(2) kusakaniza ndi kuthira
Mukusuta, kumapitiliranso ntchito yosakaniza bwino zowonjezera ndi polyethylene kusungunuka. Mapangidwe apadera apadera a screwct, monga mawonekedwe ndi kufalikira kwa ulusi womwe umasakaniza mu gawo losakanikirana, limathandizira kuti zowonjezera zizimwa mowa kwambiri. Kusakanikirana kumeneku ndi ma pulasitiki ndikofunikira kwambiri kukonza magwiridwe antchito. Sungani zosungunuka zopanda tanthauzo zitha kuwonetsetsa kuti mapaipi omwe amakhala osasinthasintha gawo lonselo ndikupewa zolakwika zakomweko kapena kusiyana kwa magwiridwe antchito. Mwachitsanzo, ma extroders omwe amapangidwa ndiMalipiro Khalani ndi zojambulajambula zomwe zakhala zikuyesani zingapo, zomwe zimapangitsa kusakaniza koyenera ndikupanga mapulogalamu ndikupanga ppe yapamwamba kwambiri.
(3) Kutumiza ndi kuwumba
Sungunulani kwathunthu komanso pulasitiki kwathunthu imapitirirabe kutsogolo ndi screw kenako ndikudutsa muawo pamutu wa Expreder. Kusungunuka kudutsa mu kufa, kumapangitsa kuti zigwirizane ndi khoma lamkati la Die, motero poyamba kupanga mawonekedwe a chitoliro. Pakadali pano, chitolirochi chidakali mu dziko lotentha kwambiri ndipo pamafunika chithandizo chinanso kukonza mawonekedwe ake ndikuwongolera momwe akuchita.
3. Kuzizirana ndi kuwumba
Chitoliro chotentha kwambiri chopangidwa ndi mafa nthawi yomweyo chimalowa dongosolo lozizira. Kuzizira kumatha kuchotsa kutentha msanga, kumawathandiza kuziziritsa ndikukhazikika mwachangu. Madzi muthanki yozizira imayenda mosalekeza kuti ikhale yolimba. Kuwongolera kwenikweni kwa liwiro lozizira komanso nthawi yozizira ndikofunikira kwambiri. Kuzizira kwambiri kumatha kuyambitsa nkhawa zamkati, zomwe zimakhudza kugwira kwake kwa nthawi yayitali; Kuzizira kwambiri kuzizira kumachepetsa mphamvu yopanga zinthu.
4. Kuloleza ndi kudula gawo
Pambuyo pozizira, chitolirochi chimakhala ndi kuvuta ndi nyonga zina, koma kumafunikirabe kusungidwa mu mzere wokhazikikaa haul pansi. Posintha liwiro lazosinthasintha ndi gulu la mawilo oyenda, liwiro la matebulo ndi makulidwe a chitoliro cha chitolirocho chitha kuwongoleredwa. Pamene chitoliro chimafika kutalika koyambirira, chida chodulira chimadula. Kulondola ndi mphamvu ya wodula Phatikizani mwachindunji kupanga ndi kutulutsa kwa chitoliro.
5.
Mapaipi opangidwa ndi saipi salowera mwachindunji koma akufunika kuyeserera kokhazikika. Zinthu zoyeserera zimaphatikizapo mawonekedwe a mapaipi, monga pali ming'alu, thovu, ndi zolakwika zina; Kulondola kwenikweni, monga mainchesi akunja, makulidwe a khoma, ndi kutalika, kuti muwone ngati akwaniritsa zofunikira; Ndipo mayesero akuthupi, monga mphamvu ya tumile, okwera nthawi yopuma, ndi mphamvu ya mphamvu.
Iii. Mavuto apano ndi zochitika za chitukuko cha pulasitiki ya China
Monga dziko lalikulu lopanga padziko lapansi, China lakwaniritsanso zinthu zabwino kwambiri m'chiuno cha pulasitiki. Opanga ambiri ogulitsa aku China mosalekeza asintha mosalekeza, ndikupanga maluso awo ambiri komanso kupanga zimbuzi zopanga misika yapanyumba komanso yapadziko lonse lapansi.
KutengaMalipiro Mwachitsanzo, monga wopanga wodziwika bwino waku China, wapanga ndalama zambiri mu kafukufukuyu ndi chitukuko. Kampaniyo ili ndi gulu lalikulu la R & D lomwe limayang'ana matekinoloje ambiri otukuka ndi njira.
Kuphatikiza apo, ndikupititsa patsogolo chilengedwe kutengera chilengedwe komanso kufunikira kwa ziphuphu zapamwamba pamsika, chipapu cha pulasitiki china cha China potukuka nthawi zonse kumangopanga mawonekedwe osankhidwa nthawi zonse ndikusintha. Kumbali ina, mabizinesi amasangalala kutetezedwa ndi chilengedwe komanso kukhazikika pakusankha zinthu zosaphika, kufufuza mosalekeza zinthu zosatheka polyethylene kapena kugwiritsa ntchito zida zopangidwa kuti zithetsetse zinthu. Komabe, posintha magwiridwe antchito, mitundu yatsopano ya zinthu zopindika zomwe zimakhala ndi zovuta, komanso kukana kwanyengo.
M'tsogolo, makanema apulasitiki a China amayembekezeredwa kupitiliza kukhalabe ndi chitukuko chabwino. Ndi kukhazikitsa mozama kwa "njira yopangidwa ku China 2025", mafakitalewo adzakulanso pamayendedwe apulasitiki ang'onoang'ono kwambiri.
Pomaliza, kupanga mapaipi a polyethylene ndi njira yovuta yokhudza maulalo angapo ndi matekinoloje angapo. Makampani apulasitiki a China akuledzera akwaniritsa kale kuchita bwino kwambiri pankhaniyi ndipo ali ndi chiyembekezo chachikulu. Kuchokera pakukonzekera mosamalitsa kwa zinthu zopangira ku pokonza bwino ndi extruder, kenako kuti kuziziritsa ndi kuwumba,kuloleza Ndipo kudula, komanso kuyendera kokhazikika ndi kuyendera, gawo lililonse limakhala ndi nzeru komanso zoyesayesa za akatswiri opanga mafakitale. Ndi kupita patsogolo kosalekeza kwaukadaulo komanso kusintha kosalekeza pakufunikira pamsika, tili ndi chifukwa chokhulupirira kuti chitoliro cha saipi chimakhala ndi mapikisano apamwamba kwambiri opangidwa ndi mafakitale amtsogolo.
