Dab tsi Cov Khoom Siv Ua Sealing Sawb?

1. Modified PVC sawb

Tus nqi kuj tsis tshua muaj nqi. Vim tias cov khoom sib txawv, tus nqi feem ntau yog 6000 yuan thiab 15000 yuan / tuj. Cov khoom lag luam qis siv cov khoom siv pov tseg, hloov cov yas, thiab cov qib siab sau, kom cov roj hmab cov tawv nqaij tsis muaj qhov tsis yooj yim, tsis yooj yim los ua qhov nyuaj, muaj qhov tsis hnov ​​tsw, thiab yooj yim rau kev tsiv teb tsaws, uas ua rau cov khoom siv daj thiab muaj kev pab lub neej luv. Ob peb lub qhov rooj thiab lub tuam txhab qhov rai hauv cov qib qis cov nqi sib tw tseem nyob hauv kev siv. Nruab nrab thiab siab kawg PVC txiav tuaj yeem ncav cuag tus txheej txheem ntsuas, thiab lub neej kev pab cuam kuj ntev dua.

Raws li cov khoom lag luam PVC muaj halogens thiab cov hlau hnyav hauv cov stabilizers, lawv tsis yoog rau kev tiv thaiv ib puag ncig. Yog li ntawd, cov tebchaws tsim tawm hauv tebchaws thiab txawv tebchaws Beijing thiab cov nroog ntug dej hiav txwv tau tshem tawm lossis txwv kev siv PVC coj cov yeeb yaj kiab.

2. Thermoplastic EPDM roj hmab sealing sawb

Kev khi hluav taws xob yog cov khoom siv tshiab tsim nyob rau hauv xyoo tas los no los ntawm kev qhia txog kev siv tshuab txawv teb chaws thiab kev tshawb fawb hauv tsev thiab kev ywj pheej. Nws yog tsuas yog siv rau tsheb qhov rooj thiab lub qhov rooj sib khi, thiab hauv xyoo tsis ntev los no tau siv rau hauv lub tsev qhov rooj thiab lub qhov rooj sib khi. Nws qhov zoo yog:

①Performance thiab kev pab cuam lub neej yog sib npaug ntawm cov vulcanized EPDM roj hmab sib khi.

ProcessingQhov kev siv lub zog hluav taws xob tsawg dua li uas muaj cov roj paug EPDM (sib npaug rau PVC).

Nws tsis muaj cov hlau hnyav xws li halogen thiab taug txhuas, thiab nws tuaj yeem hloov kho dua tom qab ob peb xyoos, uas ua tau raws li qhov yuav tsum tau ua ntawm cov ntaub ntawv ntsuab tsev.

④Qhov feem me me (tsuas yog 0.9-0.95) thiab lub qhov rais siab tau siab. Nws zoo nkaus li kev yuav cov khoom lag luam tus nqi, thiab tus nqi siv tiag yog tsawg.

3. Khoom nta:

1) Lub teeb ua kom loj dua, nthuav dav thiab ua kom tsis muaj zog, tsis muaj dej nqus (hloov ntawm cov tsoos peb-roj plaub-hnov, asphalt ntoo fir board, thiab lwm yam khoom siv). Cov khoom lag luam yog ib puag ncig zoo, yooj yim rau kev tsim kho, thiab muaj cov khoom zoo los tiv thaiv nplooj ntawv, tiv thaiv dej xau, thiab cov dej tsis ua teebmeem.

2) Kev tiv thaiv kev kub ntxhov, kev laus ua hauj, siab thiab tsis kub tsis kam +80 ℃ ~ -45 ℃, tsis ntws, tsis muaj deformation, tsis muaj embrittlement, kev pab lub neej ntev.

3) Nws muaj kev ywj pheej qhib lub xovtooj ntawm npuas, thiab cov tsos ntawm lub rooj sib txig sib xyaw tshwj xeeb yog kev sib koom ua ke zoo li lub qhov khoob li tusyees faib, thiab nws tuaj yeem nruj nreem sib khi nrog cov cement / sealant tsis muaj kev ua txhaum, hloov mus rau kev hloov pauv hauv ntuj nthuav. thiab cov ntawv cog lus, thiab ntxiv dag zog rau qhov sib koom ua ke Cov nyhuv ntawm kev sib khi nthuav dav thiab nres dej.

4. Vulcanized EPDM roj hmab sib khi sawb

Nyob rau hauv cov nqe lus ntawm kev sib khi elasticity thiab kav ntev, nws yog ntau zog dua li ntawm PVC strips. Txawm li cas los xij, vim qhov xav tau microwave vulcanization kab duab, kev ua lub zog siv hluav taws xob ntau, feem ntau ntau tshaj 20 npaug ntawm PVC ua. Cov khoom no tsis tuaj yeem rov qab siv thiab tsis yog ib puag ncig. khoom. Ntxiv rau, cov khoom sib npaug ntawm cov khoom lag luam no (siab tshaj 1.4) yog sib npaug nrog PVC (qis qis qis roj hmab EPDM roj hmab muaj qhov sib npaug loj dua) thiab cov nqi qhov rai tau zoo ib yam li PVC roj hmab sawb, thiab kev siv nqi yog tus nqi siab, uas nyuaj rau lub tuam txhab qhov rooj thiab lub qhov rais txais.
