Ultra High Pressure Resin Ntxuav Hose
Rau kev nyab xeeb thiab kev ua haujlwm yooj yim, thiab lwm yam, tam sim no vulcanization txoj kev ntawm roj hmab hose feem ntau vulcanized los ntawm vulcanization tank. Cov txheej txheem yog muab tso rau hauv lub tube embryo rau hauv lub tank vulcanization, thiab siv saturated chav los yog dej raws li lub tshav kub hloov nruab nrab rau cua sov thiab pressurization vulcanization. Qhov kub ntawm vulcanization feem ntau yog 145 ~ 153 degrees Celsius.
Raws li txoj kev pressurization ntawm lub hose, nws muab faib ua liab qab vulcanization, dej ntaub vulcanization thiab dej vulcanization.
1. liab qab vulcanization.
Paj rwb braided, qhov txhab, knitted hoses thiab coreless interlayer hoses nrog me me puab diameters feem ntau siv liab qab vulcanization. Cov txheej txheem no muaj cov txheej txheem yooj yim, kev siv zog tsawg thiab kev ua haujlwm siab, tab sis lub siab sab nraud thaum lub sij hawm vulcanization yog me dua li ntawm cladding, uas yog ib qho nyuaj rau kev tswj thiab yooj yim rau npuas, delamination, deformation thiab lwm yam teeb meem zoo tshwm sim. Cov txheej txheem kev ua haujlwm yog txhawm rau muab ob qho kawg ntawm cov roj hmab-coated tube billet kom tsis txhob delamination vim lub zog rushing nyob rau hauv lub sij hawm vulcanization, thiab muab tso rau hauv lub vulcanization ncej phaj rau vulcanization tank vulcanization.
2. qhwv cov ntaub dej rau vulcanization.
Nws yog feem ntau haum rau hose tsim los ntawm cov txheej txheem nyuaj. Lub hose dawb yog ntim rau ntawm lub tshuab peb-yob los yog lub tshuab ntim hose, muab tso rau hauv lub vulcanization thav duab, thiab rov qab nrog lub hauv ncoo mos (lub hose tsis nias thaum lub sij hawm vulcanization txheej txheem). Xa mus rau vulcanization tank rau vulcanization. Rau cov hoses nrog cov qauv tshwj xeeb thiab cov phab ntsa tuab, ntxiv rau cov ntaub dej, nws tseem yuav tsum tau siv cov hlua los yog cov xov hlau los ua kom lub zog.
3. Dej vulcanization.
Nws yog feem ntau haum rau coreless interlayer roj hmab raj. Txoj kev yog kaw ob qhov kawg ntawm lub raj dawb paug coated nrog roj hmab, tso nws tiaj tus hauv lub tank dej, ncuav dej txias ib los ntawm ib qho, ua kom lub raj lub cev tag nrho submerge nyob rau hauv dej, kom lub sab hauv thiab sab nraud siab sib npaug, xa mus rau hauv. vulcanization tank rau vulcanization. Txoj kev no thawj zaug yuav tsum tau ua kom sov cov dej hauv lub tank dej rau hauv dej superheated (feem ntau lub zog siab yog {{0}}.4 ~ 0.5MPa), thiab lub sij hawm vulcanization ntev, uas yuav siv sij hawm 2 ~ 3 teev. . Kev ua tau zoo ntawm cov qauv no ntawm vulcanization yog qis dua li ntawm liab qab vulcanization, tab sis qhov zoo ntawm cov roj hmab hose yog qhov ruaj khov.
