Cov kev qhia tshwj xeeb ntawm cov zaub mov npog feem ntau suav nrog cov khoom siv, qhov ntev, qhov kub thiab txias, kev ua haujlwm sealing, thiab kev pabcuam lub neej. Cov npog feem ntau yog tsim los ntawm cov khoom siv xws li zaub mov- qib PP yas, PE yas, lossis silicone; cov ntaub ntawv no yuav tsum muaj kev nyab xeeb, tsis yog - tshuaj lom, thiab ua raws li cov qauv rau zaub mov- tiv tauj cov khoom. Tsis tas li ntawd, cov khoom lag luam yuav tsum muaj kev pom zoo los yog hloov tau yooj yim, tso cai rau kev saib xyuas cov khoom noj hauv tsev yooj yim thaum txhim kho kev yooj yim thaum siv txhua hnub.
Cov npog zaub mov feem ntau yog tsim los kom haum rau ntau qhov ntau thiab tsawg ntawm cov tais diav -feem ntau categorized li me, nruab nrab, thiab loj- ua rau lawv haum rau ntim xws li tais, phaj, thiab khob. Qee cov khoom lag luam muaj cov npoo elastic lossis nthuav dav tsim, ua kom lawv haum rau cov tais diav ntawm ntau cov duab thiab ntau thiab tsawg; Qhov no txhim kho qhov haum thiab sealing muaj peev xwm, yog li txo qis qhov nkag ntawm huab cua, noo noo, thiab ntxhiab tsw.
Qhov kub thiab txias kuj yog lwm qhov kev qhia tseem ceeb. Cov txheej txheem yas npog feem ntau muaj qhov txias thiab kub tsis kam, ua rau lawv haum rau lub tub yees cia thiab siv txhua hnub. Cov khoom tsim los ntawm siab -kub- cov ntaub ntawv tiv taus tuaj yeem tiv taus qhov kub siab dua; Txawm li cas los xij, cov neeg siv yuav tsum ua raws li cov khoom siv cov lus qhia tshwj xeeb los tiv thaiv deformation lossis kev puas tsuaj los ntawm kev kub siab tshaj qhov txwv.
Cov zaub mov npog yuav tsum muaj cov qauv tsim muaj zog thiab kav ntev. Lawv yuav tsum muaj kev tiv thaiv zoo rau stretching thiab deformation, tswj lawv cov sealing zoo txawm tias tom qab siv dua. Thaum lub sij hawm tsim khoom, kev txheeb xyuas txog qhov zoo li, qhov tseeb qhov tseeb, kev ua tau zoo ntawm kev sib khi, thiab kev nyab xeeb ntawm cov khoom yog qhov tseem ceeb los xyuas kom meej tias cov khoom ua tau raws li cov qauv kev tsim qauv thiab ua rau cov neeg siv khoom txaus siab rau kev siv lub sijhawm ntev -.
