Cov hnab yas woven feem ntau yog siv rau kev thauj mus los. Nws cov yam ntxwv zoo sib xws yog raws li hauv qab no:
1. Lub teeb yuag. Qhov no yog ib tug yam ntxwv tseem ceeb heev. Raws li kev soj ntsuam, qhov ceev ntawm cov ntaub yas yog li ntawm 0 9-0.98 grams / cubic centimeter. Lub hnab ntim khoom siv feem ntau yog polypropylene. Piv txwv tias lub hnab yas woven tsis ntxiv muab tub lim, ces nws qhov ceev yog sib npaug rau cov polypropylene. Qhov ceev ntawm polypropylene yog 0 9-0.91 g / cm3.
2. Siab tawg lub zog. Yas woven hnab cov ntaub ntawv yog ib yam khoom uas muaj lub siab saj zawg zog cracking lub zog, uas muaj feem xyuam rau nws cov qauv molecular, degree ntawm crystallization, cua ntsawj ntshab orientation, thiab lwm yam, thiab kuj muaj feem xyuam rau hom additives. Yog tias lub zog tshwj xeeb yog siv los ntsuas cov hnab yas woven, nws yog siab rau lossis ze ntawm cov ntaub ntawv hlau
3. Zoo hnav tsis kam. Kev sib txhuam coefficient ntawm cov ntshiab polypropylene yas braids yog me me, tsuas yog hais txog 0.12, uas zoo ib yam li nylon. Rau qee qhov, kev sib txhuam ntawm cov yas braids thiab lwm yam khoom muaj cov nyhuv lubricating.
4. Cov tshuaj tiv thaiv zoo. Cov hnab yas woven muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem khaws cia rau lub sijhawm ntev hauv qhov xwm txheej ib txwm muaj. Thaum qhov kub thiab txias, carbon tetrachloride, xylene, turpentine, thiab lwm yam tuaj yeem swell nws, fuming nitric acid, fuming sulfuric acid, halogen ntsiab thiab lwm yam muaj zog oxides yuav oxidize nws, thiab nws yog resistant rau muaj zog bases thiab dav acids. Zoo corrosion kuj.
5. Muaj hluav taws xob zoo. Ntshiab polypropylene braid yog ib qho hluav taws xob zoo heev. Vim tias nws tsis nqus dej noo thiab tsis cuam tshuam los ntawm cov dej noo hauv huab cua, lub zog tawg kuj tseem siab, thiab qhov dielectric tas li yog 2.2-2.6. Txawm hais tias yas braid muaj rwb thaiv tsev zoo, qhov no tsis txhais hais tias nws tuaj yeem siv los ua cov khoom siv insulating. Nyob rau hauv qhov tseeb, lub Upper woven hnab tsis yog tag nrho insulated.
6. Kev tiv thaiv ib puag ncig. Ntawm qhov kub thiab txias, cov hnab yas woven tsis corroded los ntawm noo noo txhua. Raws li kev ntsuas cov ntaub ntawv, lawv cov dej nqus dej hauv 24 teev yog tsawg dua 0.01%, thiab lawv cov dej vapor permeability kuj tsawg heev. Txawm li cas los xij, ntawm qhov kub thiab txias, cov hnab ntim khoom yuav ua rau tawg vim ua rau nkig, yog li peb yuav tsum xyuam xim rau chav tsev kub thaum khaws cov hnab ntim khoom, tab sis lawv yuav tsis ua pwm.
