5 hli tuab dub polyurethane ntawv

Cov txheej txheem ntau lawm ntawm 5 hli tuab Dub Polyurethane daim ntawv tsuas yog cuam tshuam nrog cov kauj ruam hauv qab no:
1. Xaiv cov khoom siv raw: muaj ob qhov pib ntawm cov ntaub ntawv raw siv rau Polyurethane Boards - MDI hom thiab TDI hom. Zoo cov khoom siv raw yuav tsum tau xaiv thaum lub sijhawm cov txheej txheem ntau lawm los xyuas kom meej qhov ruaj khov ntawm cov khoom zoo.
2. Kev npaj ntawm sib tov: sib xyaw cov khoom siv raw ua ke raws li cov hardness uas yuav tsum tau ua tiav, ntom ntom, thiab lwm yam khoom.
3. Moulding: Txhaj qhov sib xyaw kom haum rau hauv cov pwm pwm thiab tsim cov paib uas yuav tsum tau los ntawm kev kub siab thiab siab moulding.
4. Kev ua dua tshiab: huv si, Debur, tshem cov plua plav, cua sov thiab lwm cov txheej txheem tom ntej ntawm cov paib tsim kom ntseeg tau tias cov khoom lag luam tau raws cov neeg siv khoom.
Cov ntsiab lus hauv qab no yuav tsum tau sau tseg thaum lub sijhawm cov txheej txheem tsim khoom:
1. Ua tib zoo rau qhov zoo thiab sib piv ntawm cov khoom nyoos, piv txwv li, tsis muaj tseeb, cov khoom siv tsis tau tuaj yeem cuam tshuam cov khoom siv thiab cov khoom;
2. Nruj ua raws li qhov xav tau ntawm cov qauv hauv tebchaws kom ntseeg tau cov khoom lag luam zoo;
3. Kev sib tw ntau lawm yuav tsum khaws cov khoom siv huv thiab huv thiab huv si thiab kev kho mob thiab kev ua haujlwm tsis tu ncua kom ntseeg tau tias cov khoom siv ruaj khov thiab ntau lawm ntawm cov khoom siv.
5 hli tuab dub polyurethane cov ntawv txheeb xyuas feem ntau siv nyob rau hauv cov xwm txheej hauv qab no:
1. Ua pwm thiab pwm pwm;
2. Siv rau tsim cov chav huv chav tsev thiab cov khoom siv ua kom pom;
3. Nws tuaj yeem siv los ua cov roj hmab lossis cov yas ntu thaum lub sijhawm tsim khoom los txhim kho lawv cov khoom tiv thaiv.
Thaum siv, cov ntsiab lus hauv qab no yuav tsum tau sau tseg hauv qab no:
1. Ua ntej siv, tshawb xyuas kom ntseeg tau tias nws qhov zoo yog lawm thiab tsis muaj kev puas tsuaj;
2. Zam kev siv nyob rau hauv ib puag ncig nrog kub, nplaim taws, lossis lwm yam xwm txheej uas yuav ua rau hluav taws;
3. Thaum siv, saib xyuas, yuav tsum tau them rau kev zam kev sib tsoo thiab kev cuam tshuam los tiv thaiv kev puas tsuaj rau lub rooj sib tw polyurethane;
4. Yog tias siv cov cua sov qis dua, nws yuav ua rau cov polyurethane kom tawv tawv thiab cuam tshuam rau nws cov khoom, thiab kev tiv thaiv yuav tsum tau coj mus rau hauv tus account.
Peb tau cog lus rau kev tsim khoom thiab tshawb fawb thiab kev txhim kho cov ntawv sau polyurethane rau ze li 20 xyoo. Cov ntawv sib txawv ntawm cov ntawv sib txawv ntawm cov ntawv txheeb yuav siv cov txheej txheem ntau lawm, thiab cov khoom sib txawv yuav siv rau hauv cov kev siv sib txawv. Peb siv cov ntaub ntawv raw ua los ntawm cov khoom siv raw manufacturers, nrog pab pawg tshaj lij thiab pab pawg ua haujlwm ntau ntxiv, thiab cov kev pabcuam tom qab muag ua rau rov qab. Ntxiv mus, ua cov chaw tsim khoom lag luam, peb tshem tawm qhov xav tau rau intermediaries, tso cai rau peb cov khoom kom muaj tus nqi tsim nyog thaum ua kom zoo. Nws tau cawm koj ntau tus nqi.

Cov ntawv sau polyurethan no yog tsim los ntawm cov khoom siv thickosetting, thiab yog li ntawd lawv tsis tuaj yeem rov ua dua tshiab lossis rov ua haujlwm tab sis lawv tuaj yeem raug ntxuav. Polyurethane Cheebtsam los ntawm cov hauv paus oxes opperuplicit cov khoom tsim los ntawm cov roj hmab thiab lwm yam khoom siv ib txwm muaj.

Puas yog pu tib yam li polyester?

Vim tias polyester muaj cov ntsiab lus muaj ntau dua ntau dua cov ntsiab lus polyurethane, Polyester cov saum npoo muaj zog ua nws yooj yim dua rau khawb thiab ntxuav tshuaj lom neeg. Txawm li cas los xij, Polyurethane hloov tau ntau dua polyester ua nws haum rau cov ntawv thov uas yooj yim yog qhov tseem ceeb

Puas yog pu zoo dua li roj hmab?

Tsis zoo li cov roj hmab, polyurethane muaj cov muaj peev xwm ntau dua, thiab kev ua kom zoo dua rau cov roj, roj, oxygen, thiab ozone.
