Chaw Tshav Kub Huab Cua Sawb Sab Thiab Sab Saum Toj

Kev ua kom zoo tshaj txhuas lub qhov rooj thiab lub qhov rais ntim roj hmab cov khoom ua haujlwm PK.

Aluminium alloy cov qhov rooj thiab qhov rais kaw ntom daim kab xev yog txawv, yuav ua li cas kom paub qhov txawv. Qhov siv lub qhov rooj thiab qhov rai siv rau hauv lub qhov rais thiab cov qhov rooj ntaub ntaub ntsa, xws li iav thiab hau, iav thiab kiv cua, lub thawv thiab cov kiv cua thiab lwm yam. Kev sib txuas ntawm qhov chaw, nws tsim tau los ntawm kev siv lub tshuab rhuav tshem tawm, qhov rooj thiab lub khwb qhov ncauj, kua, plua plav, thiab lwm yam, kom ua tiav cov qhov rooj thiab cov hluav taws kub hauv qhov hluav taws xob, lub rwb thaiv hluav taws xob, kev txuag hluav taws kub, tsis muaj dej tsis muaj dej, tsis muaj dej, thiab lwm yam zoo li, qhov rooj thiab lub qhov ncauj daim nplaum yuav tsum muaj qhov zoo dua ntais, sealing, tsis muaj huab cua, nyhuv ntawm tshav kub rwb, kev rwb thaiv tsev, thaiv qhov tsis muaj dej thiab tsis muaj dej.

Qhov rooj qhov rais sealing strip txawm hais tias qhov feem cuam me me, tab sis qhov txiav txim tsis yog me me. Inferior qhov rooj thiab lub qhov foob seev kab tshuam tsis tsuas yog tsis muaj kev tiv thaiv ib puag ncig, tsis hnov tsw ntxhiab tsw qab uas muaj, yuav ua mob rau koj lub cev, huab cua tsis zoo. Tam sim no, feem ntau siv rau txhuas txhuas lub qhov rooj thiab lub qhov khi ntawm lub tshuab hauv cov khoom siv yog: PVC, EPDM (EPDM), thermoplastic elastomer (TPV), silicone rubber, thiab lwm yam, txhua tus muaj qhov zoo thiab qhov tsis zoo ntawm kev ua tau zoo.

1. PVC daim kab xev nplaum.

Thiab tawg. Yuav welded.

Feem ntau: theem siab 1.5g / cm3; 1.6 g / cm 3 mid-range; Tsawg ntawm 1.7 g / cm3.
