Polyurethane PU Ua Npuas Ua Ntej Seem Cov Khoom Siv

Polyurethane PU ua npuas ncauj sealing strip cov khoom siv

1. Kev Ntsuas Ua Tau: Muaj ob qho tseem ceeb, kev ua yuam kev precision yuav tsum raug tswj tsis pub dhau ± 1%

(1) Kev sib txig sib txuam, ua kom muaj lub npuas ntsej muag polyurethane ua npaws PU ua kua fwj, hauv cov txheej txheem uas muaj cov txheej txheem A, B yuav tsum nyob tsis hloov, uas yog, qhov sib piv thiab qhov nruab nrab ntawm qhov qub;

(2) Txiav qhov tseeb, vim hais tias qhov kev lag luam yuav tsum yog cov tshuaj tiv thaiv ntawm cov npuas dej ua rau lub dav hlau los yog cov nplaum dawb foaming ua, yog lub sij hawm ntawm qhov kev hloov pauv tag nrho yuav ua rau muaj kev hloov hauv qhov ntim lossis thickness ntawm lub foob los yog seem

2. Muab sib tov ua ke: Muab ob txoj hlua khi rau hauv pob txha Styrofoam tuaj yeem tsim tau rau hauv polyurethane PU foam sealing strip tom qab nws yog sib xyaw ua ke nyob hauv lub taub hau ntawm lub taub hau kom zoo ib yam ntawm tag nrho cov seev cev (thaum lub sealing sawb yog txiav, cov npuas nyob hauv cross-section Qhov yuav tsum yog yam tsis zoo);

3. Ntsuas kom sov li cas: qhov kub ntawm cov khoom siv raw tuaj yeem cuam tshuam cov kua nplaum thiab qhov ceev ntawm qhov tshuaj tiv thaiv. Yog li ntawd, nws yog ib qho tsim nyog los ua kom lub cev qhuav ntawm polyurethane PU ua npuas sealing sawb thiab xyuas kom cov qoob loo ntawm polyurethane tsis muaj kev cuam tshuam ntawm lwm qhov chaw.

4. Mus kom tiav: raws li qhov loj thiab tuab ntawm casting cov kev cai, los ntawm kev tswj lub taub hau lub taub hau, ntsug, vas arc trajectory mus nqa tawm quantitative, qhov ceev ceev casting, kom qhov loj, cov duab, thickness thiab lub cev muaj peev xwm ua tau raws li cov kev cai.

Phab I hauv PU ua npuas ncauj kev lag luam zoo

1.Qhov Kev Kawm Ua Ntej: Cov pab pawg neeg thib ib hauv Roog D nyob hauv Mainland yog ib lub koom haum tshawb fawb thiab kev lag luam ntawm PU npuas seev suab hauv Suav teb. Vim nws paub zoo txog qhov kev ua tau zoo, cov cwj pwm thiab cov txheej txheem ntawm polyurethane PU foam sealing, Tus neeg yuav khoom ntau ntxiv los muab kev pab tswv yim thiab kev sib raug zoo;

2. Nqi-zoo: Piv nrog rau cov khoom siv kho hluav taws xob, peb lub tshuab polyurethane PU npuas sealing nplaum muaj qhov zoo ntawm cov nqi thiab cov kev pab cuam tom qab muag.

3. Ib qho kev pab cuam ib zaug: Division I yuav muab cov neeg tuaj yeem npaj ib qho kev daws teeb meem ib zaug.
