PP lub cev
Polypropylene yog ib qho tsis muaj taug, tsis muaj ntxhiab, tsis muaj ntxhiab, dawb dawb crystalline polymer nrog ib tug tuab ntawm 0.90 xwb - "0 91g / cm3, uas yog ib qho ntawm lub ci ntsa iab ntawm txhua yam yas. Cov dej ntim hauv cov dej tsuas yog 0.01%, lub cev qhov nyhav yog 811,000. Cov moldability zoo, tiam sis qhov sib dhos yog qhov loj (1% ~ 2.5%). Qhov siab, nws yog qhov nyuaj kom tau raws li qhov yuav tsum tau, qhov ntawm qhov khoom yog ci iab thiab yooj yim rau xim.
PP yam ntxwv
Tsis muaj kuab lom, tsis muaj ntxhiab, tsis tshua muaj zog, lub zog, kev npliag siab, kev kub hnyiab thiab kev kub ntawm lub cev yog cov zoo dua tsis tshua muaj pes tsawg polyethylene, yuav siv tau rau ntawm 100 ° C. Nws muaj cov khoom hluav taws xob zoo thiab muaj kev sib ntau thiab tsis cuam tshuam txog cov av noo, tiam sis ua rau nkig tsis kub, tsis hnav tsis taus thiab yooj yim rau lub hnub nyoog. Haum ua rau cov khoom siv dav dav, qhov chaw tiv taus qhov muaj zog thiab cov cuab yeej yaug. Cov organic kua tshuaj xws li acids thiab cov hauv paus muaj cov nyhuv me me thiab tuaj yeem siv rau hauv cov tais diav.
Polypropylene muaj ntau yam khoom zoo heev:
1. Tus ciam ntom nti yog me me, tsuas yog 0.89-0.91, uas yog ib qho ntawm cov yam sib txawv ntawm cov khoom uas muaj plastics.
2, zoo mechanical zog, ntxiv rau tej yam kuj, lwm yam khoom kho tshuab yog zoo dua polyethylene, molding kev ua haujlwm zoo.
3. Nws muaj kev kub hnyav siab thiab qhov kev siv tas mus li yuav ncav cuag 110-120 ° C.
4, cov khoom siv tshuaj zoo, tsis muaj dej txaus, thiab tsis tuaj yeem nrog cov tshuaj feem ntau.
5, qhov kev ntxhib los mos yog ntshiab, tsis muaj tshuaj lom.
6, hluav taws xob rwb thaiv tsev zoo.
7. Lub transparency ntawm polypropylene cov khoom yog zoo tshaj uas ntawm high ntom polyethylene khoom.
PP muaj ntau yam zoo tab sis kuj muaj qhov tsis zoo:
1. Cov khoom muaj kev tsis siab txias thiab txo qhov feem tsawg lub zog.
2. Cov khoom no raug rau cov laus los ntawm qhov kev txiav txim ntawm lub teeb, cua sov thiab cov pa thaum siv.
3. Cov xim tsis zoo.
4, yoojyim hlawv.
5, pluag toughness, siab zoo li qub, tsis muaj peev xim, luam tawm thiab ua tiav
