Resin Waaka Polyurethane Matting Resin
Whakaahuatanga
Ka taea e te taapiri i te kaihoko whariki te whakaheke i te kanapa o te paninga, engari ko te matingi he ngawari ki te parataiao, ka whakaiti i te pumau o te wai, a, ki te kore e rite te whakaranu, he raruraru penei i te rereketanga o te kanapa o te paninga.Na reira, hei whakatau i nga paanga kino i puta mai i te taapiringa o nga kaikawe whariki, ka anga te tangata ki te aro ki te rangahau o te kapia whariki-whaiaro polyurethane-wai me te kapia whariki polyurethane-wai-wai-a-wai me te kore e taapiri i nga kaihoko whariki.
1. Whakamate Whaiaro Te Resin Polyurethane Na te Wai
Ko te kapia whariki whaiaro e pa ana ki te kapia whakakikorua e whai hua ana ki te whariki mata i muri i te hanganga o te kiriata me te kore e taapiri atu i te paura whariki, te ware pi ranei ki te kapia paninga.He pai te hototahitanga o te kapia whariki ki etahi atu kapia me te taupae whakaata rite i muri i te hanganga o te kiriata na te mea he rite nga ahuatanga o te tinana me te matū o ona waahanga me te hanganga roopu hiko whatu me nga matūriki kaihoko whariki, e whakaoti pai ana i nga raru na te taapiri i te kaihoko whariki.I te wa ano, na te mea kaore i te whakamahia te taurangi whakaata o te kaihoko whariki taapiri me te ngota whakakikorua, kaore e taea te whai whakaaro ki nga ahuatanga o te whariki me te maamaatanga, kaore e taea te whakatutuki i nga whakaritenga tono o etahi paninga.Na reira, ko te kapia whakakikorua whakakikorua whaiaro karekau e whakamahi i tetahi kaihoko whariki o waho kua aro nui.
I whakahiatotia te kapia waikore polyurethane me te kore he kaikawe whariki ma te tikanga toronga mekameka hydrazine hydrate post chain.I roto i te tukanga o te me, ka puta nga matūriki rite ki te kaihoko whariki, a ka rere taurite nga matūriki ki runga i te mata o te kiriata whakapiri, ka taratara te mata moroiti.Ko tenei tikanga kaore i te whakaoti noa i nga hapa i puta mai i te whakamahi i te kaihoko whariki, engari he pai rawa atu te pumau o te wai, ka taea hoki te whakapai ake i te aukati mirimiri, te whakakopa me te tere mirimiri o te kiriata paninga.Ka taea te whakamahi whanui ki te paninga mata o te hiako, polyvinyl chloride (PVC) hiako, polyurethane hiako horihori, etc.
Ko te patent Hainamana cn106432667b e whakaatu ana i tetahi tikanga whakarite mo te maatete hiako hiako polyurethane whakamaarama whaiaro me te ngawari.Ka whakamahia e te patent whakarereke te hmdi, HDI Trimer, propylene carbonate glycol me te waikawa dimethylbutyric (DMBA) hei rauemi mata matua me te hydrazine hydrate hei whakaroa mekameka i muri i te whakaemulsification ki te whakarite i te polyurethane kawe wai.Ko te HDI Trimer i roto i te rauemi mata he hanganga mowhiti o nga roopu mahi e toru.Ko te hanganga mowhiti he pumau i te wa o te tukanga whakahiato, ka taea te hanga i te hanganga whatunga honohono mo etahi hua polyurethane.Ko te hototahitanga o te kiri moroiti kua hangaia me etahi atu kapia polyurethane ka heke i te wa o te hanga kiriata.I tua atu, he ahua o te tioata i roto i te polyurethane, e arai ana ki te heke o te maramatanga o te hanga kiriata, te whakatutuki i te painga o te mate o te kanohi, me te whakapai ake i te elasticity, te aukati wai, te whakarewatanga me te kakahu parenga o te kiriata polyurethane.
2. Te Whakarereketanga o te Resin Polyurethane Matting Resin
I te mea ko te taapiri o te kaihoko whariki ka pa ki nga ahuatanga tinana o te kiriata paninga, a ko nga roopu hydrophilic kei roto i te kapia polyurethane a-wai-a-wai-a-te-whaiaro ka paheke te wai o te kiriata paninga i muri i te hanganga o te kiriata wai, ina koa ka whakamahia. mo te paninga o runga o te hiako pepa ranei, he maha nga kamupene e whakarite ana i nga kapia whariki ma te whakarereketanga, penei i te whakarereketanga silicone me te whakarereke hononga-whakawhiti.
I roto i te tukanga o te hanga kiriata o te organosilicon kua whakarereketia i te wai whakakikorua i te polyurethane matting resin, ka heke nga wahanga o te organosilicon hydrophobic ki te mata o te kiriata paninga hinu ki te hanga i te mata taratara moroiti, e hanga ana i te polyurethane he mea pararopi me nga taonga pararopi, me te aukati wai, waiariki. he pai te whakapai ake i te pumau me nga taonga miihini.I whakaritea te kapia matting polyurethane ma te whakamahi i te PTMG, te diisocyanate (IPDI) me te dimethylol propionic acid (DMPA) hei rauemi mata.
Ko te whakarereketanga o te hononga whakawhiti ka huri i te hanganga o te polyurethane raina, ko te hua o tana hononga ki te hanga i nga macromolecules polyurethane whatunga kiato.Ka piki te rahi matūriki o te wai polyurethane, ka mimiti te wai i te wa o te whakamaroke o te wai.Ko nga tauira he nui ake te diameter ka hanga he mata taratara me te kanapa iti i muri i te taaputanga o tetahi ki tetahi.I te wa ano, i pai ake te parenga wera, te aukati wai me te parenga matū o te polyurethane kua rite ki te wai na te hanganga o te whatunga honohono-whiti.Ko te wai whakakikorua o te polyurethane kawe i te wai i whakarerekehia e te hononga whakawhiti o roto i whakaritea ma te tikanga toronga mekameka pou.He taratara te mata o te kiriata.
Kupu Whakamutunga
Hei waahanga nui o te tono o te kapia polyurethane wai, kua arohia e te umanga whakakikorua te kapia whakakikorua.Heoi, ko etahi o nga hua he ngoikore te pumau.I te mea kaore he take ki te taapiri i te kaihoko whariki i roto i te paninga, he kaha te pumau o te kapia whakakikorua whaiaro me te pai o te mahi whakakikorua, ka noho hei ahua whanaketanga a meake nei.
