PVC hose ntau lawm kab nyob rau hauv cov txheej txheem ntau lawm yuav inevitably muaj ib co tsis ua hauj lwm, xws li: txheej txheej ntawm cov yas yeeb nkab yog ntxhib thiab unsmooth, los kho cov txheej txheem kub nyob rau hauv lub sij hawm; Phab ntsa thickness ntawm cov yeeb nkab tsis sib npaug, kho cov phab ntsa thickness ntawm cov pwm; Muaj cov grooves nyob rau sab hauv ntawm cov yeeb nkab, xyuas seb cov yeeb nkab sab hauv puas tau nkag mus rau hauv dej thiab txo qhov kub ntawm cov pwm. Sab nrauv ntawm cov yeeb nkab yas uas tsim los ntawm PVC hose ntau lawm kab muaj grooves, thiab cov dej qhov hluav taws xob siab ntawm lub tes tsho sizing yog kho, thiab cov dej tso tawm yuav tsum sib npaug.
Koj tuaj yeem nkag siab tias cov kav dej yas ua los ntawm PVC hose ntau lawm kab yuav muaj kev cuam tshuam tsis zoo, tsis muaj zog tensile thiab toughness, feem ntau manifested li nkig, tsis tshua muaj elongation thiab yooj yim tawg. Tsis tas li ntawd, qhov softening kub yog tsawg, yooj yim rau deform thaum rhuab, thiab txo qhov cuam tshuam tsis kam, tensile zog thiab toughness ntawm cov yeeb nkab.
