nkhani

Mapulasitiki a polyvinyl kolorayidi ali ndi mitundu yosiyanasiyana, kusiyana kwakukulu, ndi njira zosiyanasiyana zogwirira ntchito, zomwe zingathe kukanikizidwa, kutulutsa, jekeseni, zokutira, etc. PVC pulasitiki nthawi zambiri imagwiritsidwa ntchito popanga filimu, zikopa zopangira, waya ndi chingwe chotchinjiriza, zolimba. mankhwala, pansi, mipando, zipangizo masewera ndi zina zotero

Mankhwala a PVC polyvinyl chloride amatha kugawidwa m'magulu awiri olimba komanso ofewa.Zopangira zolimba zimakonzedwa popanda plasticizer, pomwe zofewa zimakonzedwa ndi pulasitiki wambiri.PVC polyvinyl chloride poyamba ndi pulasitiki yolimba, kutentha kwake kwa galasi ndi 80 ~ 85 ℃.Pambuyo powonjezera pulasitiki, kutentha kwa galasi kungathe kuchepetsedwa, komwe kumakhala koyenera kuti pakhale kutentha pang'ono, kotero kuti kusinthasintha ndi pulasitiki ya unyolo wa maselo kukhoza kuwonjezeka, ndipo kungapangidwe kukhala zofewa zofewa kutentha.Kuchuluka kwa plasticizer kuwonjezeredwa ku pulasitiki yofewa ya PVC ndi 30% ~ 70% ya PVC.

PVC polyvinyl chloride mu processing anawonjezera plasticizer, stabilizer, lubricant, colorant, filler, akhoza kukonzedwa mu mbiri zosiyanasiyana ndi mankhwala.Ntchito zenizeni za PVC ndi izi:

1, mbiri ya PVC,

GAWO, GAWO LAPADERA NDI NTCHITO YAIKULU PAMENE NTCHITO YA PVC M'DZIKO LATHU, AKAUNTI PA 25% YA NTCHITO YONSE YONSE PA PVC, IMAKAMA AMAGWIRITSA NTCHITO KUPANGA ZIPANGIZO NDI MAwindo ndi Zipangizo Zopulumutsira MPHAMVU, PAKATI PA TSOPANO. FUKO LONSE LAKALI LAKUKULA KWAMBIRI.

2. PVC chitoliro

Chitoliro cha PVC ndi gawo lachiwiri lalikulu la ogula la PVC, lomwe limawerengera pafupifupi 20% yazakudya zake.M'dziko lathu, chitoliro cha PVC chapangidwa kale kuposa chitoliro cha polyethylene (PE) ndi chitoliro cha polypropylene (PP), pali mitundu yambiri, ntchito yabwino kwambiri, yogwiritsidwa ntchito komanso yofunika kwambiri pamsika.

3. Kanema wa PVC

Kanema wa PVC ndiye gawo lachitatu lalikulu la ogula la PVC, lomwe limawerengera pafupifupi 10% ya zomwe amadya.Kugwiritsa ntchito kalendala kungakhale PVC yopangidwa mu makulidwe odziwika a filimu yowonekera kapena yamitundu, filimu yopangidwa ndi njirayi imatchedwa filimu ya kalendala.The granular zopangira PVC akhoza kuwomberedwa mu filimu ndi kuwomba akamaumba makina, ndi filimu opangidwa ndi njira imeneyi amatchedwa blowpulasitiki film.Filimu yopyapyala ndiyothandiza kwambiri.Itha kusinthidwa kukhala matumba onyamula, malaya amvula, nsalu zapatebulo, makatani, zoseweretsa zokhala ndi inflatable ndi zina zotero podula ndi kulumikiza kutentha.The lonse mandala filimu angagwiritsidwe ntchito kumanga greenhouses ndi pulasitiki greenhouses, kapena mulch.

4, PVC bolodi ndi pepala

PVC onjezerani stabilizer, lubricant ndi filler, mutatha kusakaniza, extruder imatha kutulutsa mitundu yosiyanasiyana ya chitoliro cholimba, chitoliro chowoneka bwino, mvuto, chomwe chimagwiritsidwa ntchito ngati chitoliro chotsika, chitoliro chamadzi, malaya a waya kapena masitepe.Mapepala olimba a makulidwe osiyanasiyana amatha kupangidwa mwa kukanikiza kotentha pamapepala a laminated.The pepala akhoza kudula mu mawonekedwe ankafuna, ndiyeno PVC kuwotcherera ndodo ntchito kuwotcherera mu zosiyanasiyana mankhwala dzimbiri zosagwira akasinja yosungirako, ngalande mpweya ndi muli ndi mpweya wotentha.

5, zinthu zofewa za PVC

Kugwiritsa ntchito extruder akhoza kufinyidwa mu hoses, zingwe, mawaya, etc. Kugwiritsa jekeseni akamaumba makina ndi zisamere pachakudya zosiyanasiyana, nsapato pulasitiki, zitsulo, slippers, zidole, Chalk galimoto, etc.

6. PVC ma CD zipangizo

PVC mankhwala zimagwiritsa ntchito ma CD mu muli zosiyanasiyana, mafilimu ndi zidutswa zolimba.Zotengera za PVC zimapanga madzi amchere, zakumwa, mabotolo odzola, omwe amagwiritsidwanso ntchito pakuyika mafuta oyengeka.

7. PVC siding ndi pansi

PVC siding imagwiritsidwa ntchito makamaka m'malo mwa aluminiyamu siding.Kuphatikiza pa mbali ya PVC utomoni, zigawo zotsala za matailosi PVC pansi ndi zipangizo zobwezerezedwanso, zomatira, fillers ndi zigawo zina, makamaka ntchito mu bwalo la ndege otsiriza pansi ndi malo ena olimba pansi.

8, PVC ogula katundu

Zogulitsa za PVC zitha kupezeka kulikonse m'moyo wathu watsiku ndi tsiku.PVC imagwiritsidwa ntchito popanga zikopa zosiyanasiyana zotengera katundu, zinthu zamasewera monga basketball, mpira ndi rugby.Malamba angagwiritsidwenso ntchito popanga mayunifolomu ndi zida zapadera zodzitetezera.Nsalu za PVC zopangira zovala nthawi zambiri zimakhala nsalu zoyamwa (zopanda zokutira), monga ma poncho, mathalauza amwana, ma jekete achikopa oyerekeza ndi nsapato zamvula zosiyanasiyana.PVC imagwiritsidwanso ntchito pazinthu zambiri zamasewera ndi zosangalatsa, monga zoseweretsa, zolemba ndi zinthu zamasewera.
