PU pob zeb yog dab tsi?

PU pob zeb, tseem hu ua polyurethane pob zeb, yog cov khoom siv hluavtaws uas tau txais kev nyiam nyob rau xyoo tas los no los ua lwm txoj hauv kev rau pob zeb ntuj. Nws yog dav siv nyob rau hauv ntau yam kev siv, nrog rau kev tsim kho, tsim sab hauv, thiab tsim rooj tog. Tab sis dab tsi yog PU pob zeb ua los ntawm? Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv lub ntiaj teb fascinating ntawm PU pob zeb thiab tshawb txog nws muaj pes tsawg leeg thiab cov khoom.

Lus Txhais thiab Kev Sib Sau ntawm PU Pob Zeb

PU pob zeb yog ib hom pob zeb dag ua los ntawm polyurethane, ntau yam khoom siv yas. Polyurethane yog tsim los ntawm reacting ob lub ntsiab Cheebtsam: ib tug polyol thiab ib tug isocyanate. Cov khoom siv no tau sib xyaw ua ke los ua ib qho polymer, ua rau cov khoom siv ruaj khov thiab hloov tau yooj yim.

Cov khoom siv polyol hauv PU pob zeb feem ntau yog muab los ntawm cov roj av thiab tuaj yeem yog polyester lossis polyether. Cov polyols ua raws li cov pob txha ntawm polyurethane molecule thiab muab cov khoom muaj zog thiab resilience. Lub caij no, cov khoom siv isocyanate feem ntau yog muab los ntawm cov roj av lossis cov nkev ntuj, thiab nws ua raws li tus neeg sawv cev sib txuas uas txuas cov polyols ua ke, tsim cov qauv tsim.

Ntxiv rau polyols thiab isocyanates, lwm yam tshuaj yuav raug ntxiv los txhim kho cov khoom ntawm PU pob zeb. Cov no muaj xws li surfactants, catalysts, tshuab tshuab, thiab fillers. Surfactants pab txo qhov nro saum npoo thiab txhim kho cov dej ntws ntawm polyurethane sib tov thaum tsim khoom. Cov catalysts tau ntxiv kom nrawm cov tshuaj tiv thaiv ntawm polyols thiab isocyanates. Cov tshuaj tshuab tshuab tsim cov npuas lossis cov hlwb hauv cov khoom, txo nws qhov ntom thiab qhov hnyav. Thaum kawg, cov fillers xws li calcium carbonate lossis silica yog ntxiv los ua kom lub zog thiab ruaj khov ntawm PU pob zeb.

Kev tsim cov txheej txheem ntawm PU pob zeb

Kev tsim cov txheej txheem ntawm PU pob zeb suav nrog ob peb kauj ruam, suav nrog kev sib xyaw, nchuav, thiab kho. Ntawm no yog ib tug luv luv lub ntsiab lus ntawm yuav ua li cas PU pob zeb ua:

1. Kev sib xyaw: Cov khoom siv polyol, isocyanate tivthaiv, thiab lwm yam khoom siv ntxiv yog sib xyaw ua ke hauv cov khoom sib luag. Qhov sib tov no yog hu ua polyurethane system.

2. Pouring: Lub kaw lus polyurethane yog poured rau hauv pwm los yog mus rau qhov chaw npaj. Cov pwm tuaj yeem ua los ntawm ntau yam ntaub ntawv, xws li silicone, roj hmab, lossis fiberglass, nyob ntawm seb qhov kev xav tau thiab kev ntxhib los mos ntawm cov khoom kawg.

3. Kev Kho: Cov khoom sib xyaw polyurethane dhau los ua cov txheej txheem kho, thaum lub sijhawm cov polyols thiab isocyanates hnov ​​​​mob los tsim cov qauv khoom. Lub sijhawm kho tuaj yeem sib txawv raws li qhov kub thiab txias, av noo, thiab cov txheej txheem polyurethane tshwj xeeb siv.

4. Demolding: Thaum lub pob zeb PU tau kho tag nrho, nws raug tshem tawm ntawm cov pwm. Cov khoom demolded tej zaum yuav raug cov txheej txheem ntxiv, xws li trimming, sanding, lossis painting, kom ua tiav qhov xav tau.

Khoom ntawm PU Pob Zeb

PU pob zeb muaj ntau yam khoom tshwj xeeb uas ua rau nws xaiv tau rau ntau yam kev siv. Qee yam ntawm cov khoom no muaj xws li:
