Tikuchita makora chomene pakupeleka -vyapachanya OEM na ODMvyakumazga vya ŵanyithu,

kukhozgeka na kudumura-tekinoloje ya mphepete na luso lwa kupanga vinthu vyakukwana.

Iwo ulipo mu phala, maji panji thovu, wakukhumba yayi kusakanizga pa-malo. Iwo ukumalizga nchito ya kuchizga mwa kukhwaska chinyezi mu mlengalenga (panji magulu ghakugwira ntchito pa vigaŵa vyapasi), kupanga chinthu chakukhora icho chili na elasticity, kukhora panji kumatira. Kapangidwe kake ka maselo kali na magulu gha urethane (-NHCOO-), agho ghakupereka vinthu ivi kuŵa na vinthu viwemi vyakupangika na makina, kuzizipizga nyengo na kumatira, ndipo ivi vikupangiska kuti vigwiriskike nchito comene mu minda nga nkhusindikizga, kuŵika pamoza, kuvikilira maji na kupanga thovu. mukuti mtundu wake umoza-chigaŵa ndipo self-kuchizga nthowa yikuchita ntchito yikuru chomene pakuzenga. Pa nyengo yakugwiliskira nchito, yingacizga mwaluŵiro na wovwiri wa vinthu vya kuwaro, nga ni chinyezi na kutentha, ndipo ivi vikupangiska kuti ndalama zakuzenga zichepeskeke makora na kupanga chinthu cha polima icho chikuŵa chakukhora, chakukhora, ndiposo chakukhora.

One-chigaŵa cha polyurethane, na mikhaliro ya "kunozgeka -ku-kugwiriskira ncito, kugwira nchito mwakugomezgeka na vithuzithuzi vyakugwiriskira ncito vinandi", yazgoka nthowa yiwemi yakunjilirapo pa vinthu vyakale (nga ni labala, asphalt, vyakusungunura-vyakumatira) mu kupanga mafakitale na uinjiniya. Makamaka apo ivyo vikukhumbikwa kuti munthu wazenge makora na kuvikilira chilengiwa vikusazgikira, nchito yake yikulutilira kukura.

Chimoza -chigaŵa cha polyurethane sealant chikutipa vyakuchitika vyambura kulindilirika kufuma ku kawonekero kake pera yayi ku katundu wake na uwemi wake pakugwiliskira ntchito.

Fomu

Phala, kuchizga mu elastomer pa kutentha kwa chipinda;

Katundu

Kuŵa wakukhora chomene (kutalikirana pa kupumura 300%-600%), kukana maji na nyengo, nkhwakwenelera kusindikizga viŵaro vyakuzenga na vigaŵa vya galimoto;

Uwemi

Palije pa-site proportioning iyo yikukhumbikwa pa nyengo ya kuzenga, yakunozgeka kugwiliskira nchito para yafumiskika, ndipo yikukwaniska kuzgoŵera kusunkhunyika kwa substrate para yachizga.

Kuchizga

Nyengo yakuwumira pa charu chapasi 20-60 mphindi, kuchizga kwakukwana kukutora maora 24-72 .

Kugwira ntchito kwa chilengiwa

Chigaŵa chimoza-chigaŵa cha polyurethane chikugwira ntchito makora chomene pa chilengiwa, chikukwaniska ivyo vikukhumbikwa mu GB/T 13477-2020 standard, chili na VOC iyo yili pasi pa 50g/L, chilije vyakusungunula vya benzene, phula na vyakuwonjezera vya visulo vyakuzirwa, ndipo chingagwiliskirika ntchito kwa nyengo yitali.

Kuti mugwiriskirenge ncito makora cigaŵa cimoza ca polyurethane, nchakuzirwa comene kumanya umo vikuŵira. Pansi apa pali kulongosora mwakudumura umo vikugwilira ntchito kwizira mu "kuchizga kwa chinyezi":

Kuchizga pamwamba

Pamanyuma pa kufumiska, chigaŵa cha pachanya cha sealant chikuchita dankha na H2O mu mlengalenga, kupanga mabond gha urea na kufwatura CO2, kupanga filimu ya pachanya ya elastic. Ndondomeko iyi kanandi yikutora maora 0-24.

Kuchizga kwamukati

Pakupita kwa nyengo, chinyezi chikunjira mu chigaŵa chakumatira ndipo chikulutilira kuchita na -NCO bonds mukati chomene. Nkhongono na kukhora vikufika pa mlingo uwo vikapangika pachokopachoko. Ndondomeko iyi njakutali chomene, kanandi yikutora mazuŵa 1-7.

Kuchizga kwakukwana

Ici cikung’anamura kuti chigaŵa chakumatira chikukolerana chomene na mtanda- mukati na kuwaro, ndipo ivi vikupangiska kuti chiŵe chakukhora chomene.

Para mukusunga chinthu chimoza-chigaŵa cha polyurethane, nchakukhumbikwa kuti muŵe na nyengo yakuzizima pakati pa 5-30℃na kupeŵa ungweru wa dazi, nyengo yakuzizima chomene, na chinyezi. Para mukusankha polyurethane wa chigaŵa chimoza, ghanaghaniranipo pa chigaŵa chake. Nthowa zakwenelera zakukolerana zikusazgapo vitsulo, simenti, pulasitiki, na vyakugwiriskira ntchito kuwaro. Kuti mugwiriskiyengi ntchitu kuwaro, wonani umo vikuzizipizgiya ndi nyengu ndipuso mo UV yingachitiya. Chisankho chiwemi chomene ntchakuti chikwenelera malo agho munthu wakukhala.
