Dab Tsi PU TIM?

PU tawv yog hu ua tawv polyurethane, uas yog cov tawv cua ua los ntawm cov khoom siv hluav taws xob polyurethane. PU tawv yog ib qho tawv uas ib txwm muaj, xws li cov khaub ncaws kev lag luam, cov khau khiab, khoom siv tsheb, ntim thiab lwm yam lag luam.

Yog li ntawd, PU tawv tawv ua ib txoj haujlwm tseem ceeb heev hauv kev ua lag luam tawv.

Los ntawm cov txheej txheem ntau lawm thiab ib puag ncig kev tiv thaiv lub tswv yim, PU tawv yog faib ua ob hom khoom siv PU thiab cov tawv nqaij.

Dab tsi yog qhov sib txawv ntawm ob hom tawv?

Cia peb saib thawj zaug ntawm qhov sib txawv hauv lawv cov txheej txheem ntau lawm.

Tsoos Pu Tawv Txheej Txheem:

1. Thawj kauj ruam nyob rau hauv kev tsim cov tawv tawv yog ua polyurethane, thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester

2. Txheej ntawm substrate, polyurethane resin coated ntawm substrate, raws li cov npoo tawv, xws li cov paj rwb, thiab lwm yam khoom siv hluavtaws.

3. Ua thiab Kho, cov coated substrate yog kev ua tiav thiab kho, luam ntawv, luam tawm, luam tawm cov txheej txheem xav tau, xim thiab cov nyhuv npoo thiab nto. Cov kauj ruam ntawm cov txheej txheem no tuaj yeem ua rau tawv zoo dua li cov tawv tiag, lossis muaj cov qauv tshwj xeeb.

4. Tom qab kev kho mob: Tom qab ua tiav kev ua tiav, PU tawv nqaij yuav xav tau kev tiv thaiv kab, kev tiv thaiv dej, txhawm rau txhim kho nws cov cwj pwm ruaj khov thiab cov yam ntxwv.

5. Tswjhwm Xyuas Zoo: Txhua txhua theem ntawm kev tsim khoom, kev tswj kom zoo thiab tshuaj xyuas yuav nqa tawm kom ntseeg tau tias PU tawv ua tau raws li kev tsim qauv thiab cov kev cai tshwj xeeb.

Cov txheej txheem ntau lawm ntawm cov rov ua dua pU tawv:

1. Sau thiab cov khoom siv khib nyiab thiab cov khoom siv tawv tawv, tom qab txheeb thiab ua haujlwm tu thiab av, thiab tom qab ntawd ua kom qhuav kho;

2. Pulverize cov khoom siv huv polyurethane mus rau hauv cov khoom me me lossis hmoov;

3. Use a mixer to mix polyurethane particles or powders with polyurethane prepolymers, fillers, plasticizers, antioxidants, etc., and then put them into the heating equipment for chemical reaction to form a new polyurethane matrix. Lub polyurethane latrix yog tom qab ntawd ua rau hauv zaj duab xis lossis cov duab teev los ntawm casting, txheej lossis calendering.

4. Cov khoom tsim tau yog rhuab, txias thiab kho kom paub tseeb tias cov khoom siv lub cev thiab tshuaj ruaj khov.

5. Kho cov khoom siv ua PU Tawv, embossed, coated, dyed, dyed thiab lwm yam kev kho mob saum npoo kom tau txais cov kev xav tau thiab kev ntxhib los mos;

6. Ua kev kuaj xyuas zoo kom ua rau nws ua tiav cov qauv kev tsim nyog thiab cov tseev kom muaj. Tom qab ntawd raws li cov neeg siv khoom yuav tsum tau, txiav rau ntau qhov sib txawv thiab cov duab ua tiav lawm;

Through the production process, it can be understood that compared with traditional pu leather, recycled pu leather pays more attention to environmental protection and resource recycling, reducing environmental pollution. Peb muaj cov ntawv pov thawj grs rau pU thiab pvc tawv, uas muaj rau lub tswv yim ntawm kev tiv thaiv kev loj hlob thiab kev tiv thaiv ib puag ncig, thiab xyaum hauv tawv ntau lawm.
