Cov Zoo ntawm Kev Siv Cov Khoom Siv EPP hauv Cov Tshuab Ua Pa Tshiab

Cov khoom siv EPP yog dab tsi?

EPP yog lub npe luv ntawm polypropylene nthuav dav, ib hom yas ua npuas ncauj tshiab. EPP yog cov khoom siv ua npuas ncauj polypropylene, uas yog cov khoom siv polymer / roj sib xyaw ua ke muaj kev ua tau zoo. Nrog nws qhov kev ua tau zoo tshwj xeeb thiab zoo dua, nws tau dhau los ua hom tshiab ntawm kev sib xyaw ua ke thiab cov khoom siv rwb thaiv tsev uas loj hlob sai tshaj plaws thiab tsis ua rau ib puag ncig puas tsuaj. Lub caij no, EPP kuj yog cov khoom siv ib puag ncig uas tuaj yeem rov ua dua tshiab, lwj tag nrho, thiab tsis ua rau muaj kuab paug dawb.

Cov yam ntxwv ntawm EPP yog dab tsi?

Ua ib hom yas ua npuas ncauj tshiab, EPP muaj cov yam ntxwv ntawm lub teeb pom kev zoo, zoo elasticity, tiv taus kev poob siab thiab kev sib zog, siab rov qab deformation, zoo nqus tau zoo, tsis kam roj, tsis kam kua qaub, tsis kam alkali, tsis kam rau ntau yam tshuaj lom neeg, tsis nqus dej, rwb thaiv tsev, tsis kam kub (-40 ~ 130 ℃), tsis muaj tshuaj lom thiab tsis qab. Nws tuaj yeem rov ua dua 100% thiab yuav luag tsis muaj kev puas tsuaj ntawm kev ua tau zoo. Nws yog ib qho yas ua npuas ncauj uas zoo rau ib puag ncig. Cov hlaws EPP tuaj yeem pwm rau ntau yam duab ntawm cov khoom EPP hauv pwm ntawm lub tshuab molding.

Cov txiaj ntsig ntawm kev siv yog dab tsi?EPP hauv cov tshuab cua ntshiab?

1. Kev rwb thaiv suab thiab txo suab nrov: EPP muaj cov nyhuv rwb thaiv suab zoo, uas tuaj yeem txo qhov suab nrov ntawm lub tshuab. Lub suab nrov ntawm lub tshuab cua ntshiab siv cov khoom siv EPP yuav qis dua;

2. Kev rwb thaiv tsev thiab tiv thaiv kev ua kom dej noo: EPP muaj cov txiaj ntsig rwb thaiv tsev zoo heev, uas tuaj yeem tiv thaiv kev ua kom dej noo lossis dej khov hauv lub tshuab. Tsis tas li ntawd, tsis tas yuav ntxiv cov khoom rwb thaiv tsev hauv lub tshuab, uas tuaj yeem siv qhov chaw sab hauv zoo dua thiab txo qhov ntim ntawm lub tshuab;

3. Kev tiv thaiv av qeeg thiab compressive: EPP muaj kev tiv thaiv av qeeg muaj zog thiab tshwj xeeb tshaj yog ruaj khov, uas tuaj yeem zam kev puas tsuaj rau lub cev muaj zog thiab lwm yam khoom sab hauv thaum lub sijhawm thauj mus los;

4. Sib dua: EPP sib dua li cov khoom yas tib yam. Tsis tas yuav muaj cov thav duab hlau lossis cov thav duab yas ntxiv, thiab vim tias cov qauv ntawm EPP yog tsim los ntawm cov cuab yeej sib tsoo, qhov chaw ntawm txhua cov qauv sab hauv yog qhov tseeb heev.
