Zipangizo 5 zapulasitiki zofala kwambiri zopangira waya ndi chingwe

Ngakhale mitundu ya wayandi chingwendi osiyanasiyana, koma kapangidwe kake ka zinthuzo ndi kofanana, zinthu zomwe zimagwiritsidwa ntchito ndizofanana, zinthu zodziwika bwino zimaphatikizapo zinthu zoyendetsera mpweya, zinthu zotetezera kutentha, zinthu zotetezera, zinthu zodzaza, ndi zina zotero, komanso zinthu zotetezera kutentha.ChingweMalinga ndi makhalidwe awo osiyanasiyana, zinthu zopangira zitsulo, monga aluminiyamu yamkuwa, aluminiyamu ya aluminiyamu, ndi zinthu zopangira pulasitiki. Mitundu 5 ya zinthu zopangira pulasitiki zomwe zimagwiritsidwa ntchito kwambiri muzinthu izi ndi PVC yodziwika bwino, PE, PP, ndi zina zotero.wayandi chingwe.

1. PVC, ndi zipangizo zopangira pulasitiki zomwe zimagwiritsidwa ntchito kwambiri mu waya ndi Chingwe, PVC nthawi zambiri imagwiritsidwa ntchito poteteza waya ndi chingwe, izi zili choncho chifukwa PVC ili ndi zinthu zambiri zabwino zotetezera zomwe zimatha kuteteza waya ndi chingwe mkati, monga PVC si yosavuta kuyaka, kukana ukalamba, kukana mafuta, kukana dzimbiri kwa mankhwala, kukana kugunda. Makhalidwe amenewa amachititsa kuti ikhale ndi mphamvu yabwino yodzipatula komanso yoteteza, kotero zipangizo zonse zotetezera waya ndi chingwe nthawi zambiri zimakhala zinthu za PVC.

2. YAYANKHA(Polyethylene), mawonekedwe ake akuthupi ndi kapangidwe koyera kowala ngati sera, kamakhala ndi kusinthasintha kwabwino, kamatha kutambasulidwa kutalika kwina, kopepuka kuposa madzi, kopanda poizoni, koma poyerekeza ndi PVC, polyethylene imakhala yosavuta kuyaka. Ngakhale itachoka pamoto, imakhalabe yoyaka, polyethylene ilinso ndi mitundu yambiri yokulirapo, kuphatikiza LDPE, MDPE, HDPE, LDPE ndi imodzi mwa mitundu yotsika kwambiri, yomwe imadziwika kuti polyethylene yotsika, komanso yosinthasintha bwino. MDPE ndi polyethylene yocheperako, yomwe imadziwika kuti polyethylene yopanikizika pang'ono, magwiridwe antchito ake ndi polyethylene yokhuthala kwambiri ndizofanana. HDPE imadziwikanso kuti polyethylene yokhuthala kwambiri, magwiridwe antchito ake ndi apamwamba kwambiri, makamaka kukana kutentha ndi mphamvu zamakanika zonse zakonzedwa bwino. Polyethylene ili ndi mphamvu zabwino kwambiri zamagetsi ndipo imagwiritsidwa ntchito kwambiri pakuteteza zingwe zolumikizirana.

3. Eva(ethylene - vinyl acetate copolymer), ndi thermoplastic yofanana ndi rabara, magwiridwe ake ndi kuchuluka kwa vinyl acetate (VA) kuli ndi ubale wabwino, kuchuluka kwa VA kumakhala kochepa ngati polyethylene, kuchuluka kwa zinthu kumakhala kofanana ndi mawonekedwe a rabara, EVA imakhala ndi kusinthasintha kwabwino komanso kukana kutentha kochepa, komanso kukana mankhwala. Ngakhale ikasakanizidwa ndi LDPE, imatha kukonza vuto lakuti LDPE ndi yosavuta kusweka, ndipo kukana kugwedezeka, kufewa ndi kuuma, komanso kugwirizana pakati pa conductor ndi insulation kumatha kulumikizidwa bwino ndikulimba.

4. PP(Polypropylene)Ndi yomwe ili ndi gawo laling'ono kwambiri pakati pa mapulasitiki omwe amagwiritsidwa ntchito kwambiri masiku ano, mphamvu yamakina yapamwamba, kukana kutentha kochepa, kukana kukalamba ndikwabwino kwambiri, kuphatikiza mphamvu ya kuwonongeka kwakukulu, mawonekedwe otsika a kuyamwa madzi, zinthu za PP zimatha kukhala zoyenerera bwino malo azinthu zotetezera kutentha kwambiri.

5. Polyester, mtundu uwu wa zinthu umadziwika ndi kukana misozi kwambiri, kukana kuvala kwambiri, kusinthasintha kwakukulu komanso kukana hysteresis kochepa, malire apamwamba a kutentha komwe kumagwiritsidwa ntchito amatha kufika madigiri Celsius 1500, zomwe ndi zochulukirapo kuposa mphira ina ya thermoplastic, komanso zimakhala ndi kukana mafuta bwino komanso kukana zosungunulira.

Boying ndi katswiri chingwe wogulitsa ndi gulu lodziwa zambiri, kupereka mitundu yonse ya chingwe ndi chingwe cha wayaNgati mukufunafuna chingwe chapadera, Boying ali ndi yankho lopangidwira inu.
