Ko te painga o te "Tackifier" ki te tono o te cellulose ether i roto i te kumete

Ethers Cellulose, ina koa nga etero hypromellose, he waahanga nui o nga moata arumoni. Mo te cellulose ether, he tohu nui tona pokey mo nga umanga whakangao kumete, kua tata te pokey teitei te tono taketake mo te umanga moata. Na te awe o te hangarau, te mahi me nga taputapu, he uaua ki te whakapumau i te pokey teitei o te whareether cellulosehua mo te wa roa. Ka whakamahia te cellulose ether hei kaihoko pupuri wai, hei whakakaha me te here i roto i nga hua moata, he nui te awe ki runga i te mahi whakahaere, te pokey maku, te wa mahi me te ahua hanga o te punaha kumete. Ko enei mahi e tino whakatutukihia ana e te hononga hauwai i waenga i te ngota ngota cellulose ether me te ngota wai me te mahi awhiowhio o te ngota ngota cellulose eter, inaa, ka tangohia e ia tetahi waahanga o te here hauwai i roto i te mekameka ngota ngota cellulose ether me te ngoikore i te awhi o te cellulose ether, ka ngoikore te pupuri wai me te kaha makuku o te cellulose ether. Ko nga kaihanga moata te nuinga kaore i te mohio ki tenei waahanga, i tetahi taha, he uaua tonu nga hua moata o te whare, kaore ano kia tupato ki te aro ki te waahi o te mahi whakahaere, i tetahi atu taha, ka whiriwhirihia e maatau te nui ake o te viscosity. atu i te pokey e hiahiatia ana hangarau, ka utua ano hoki tenei waahanga mo te ngaro o te pupuri wai, engari i roto i te wettability kua pakaru.

Ko te mahi o te kumete e awehia ana e te cellulose ether kei roto i te tangohanga piri i roto i te mahi whakaputa, i roto i tenei pepa, ko te rereketanga o te kaha piri i waenga i te hua cellulose me te hua cellulose ether kua taapirihia me te tackifier i roto i te whakapiri tira uku i whakamanahia e nga whakamatautau. Ko te Tackifier tetahi momo rauemi kua taapirihia e etahi kaihanga etera cellulose kia pai ai te kore o te hanga hangarau, hangarau me nga taputapu. Ko te noho o te tackifier ka hanga i nga ngota ngota mekameka roa o te cellulose ether cross-link, ka rite ki te kupenga, ka pa ki te tere o te hanga kiriata cellulose ether me te ahua o te kiriata, na reira ka pa ki te mahi a te cellulose ether i roto i te kumete, te tika- Ko te awe o te tirohanga: kua rereke te kaha o te whakapiri i raro i ia ahuatanga whakaora; ka roa te wa whakanoho o te kumete.

1.I raro i te ahua o te rongoa paerewa, ko te taapiri o te tackifier me te cellulose ether kaore he tackifier i roto i te tukanga whakaputa ka whai paanga ki te kaha o te kaha o te whakapiri o te tira raima, ko nga hua kua taapirihia me te tackifier i roto i te tukanga whakaputa he kaha te kaha o te whakapiri. .

2.I roto i te ahua o te aukati wai, ko te kaha o te kaha o te whakapiri o te tira raima me te cellulose ether te taapiri i te tackifier i roto i te tukanga whakaputa he kino atu i tera o te hua kaore he tackifier i roto i te tukanga whakaputa noa, ko te cellulose ether kei roto te tackifier ka pa ki te wai. te ātete o te whakapiri tira.

3.I roto i nga korero mo te wa whakarite hau,ether celluloseme te tackifier i whakamahia i roto i te taapiri taera, he iti ake te kaha o te whakapiri i te hua o te hua kaore he tackifier, a ka poto te wa whakatuwhera.

4.Mo te wa whakarite, he tere ake te tere whakaora o te cellulose ether ceramic tile adhesive me te kore e taapiri i te tackifier i raro i nga mahi whakaputa noa. I roto i te whakarāpopototanga, te aroaro o te tackifier, te mahi ripeka-hono o e hanga te cellulose ether wairewa wai he nui ake te aukati steric, e whakaatuhia ana he teitei ake i roto i te whakamatautau, engari ko te noho o te tackifier ka pa ki te maha o nga waahanga tono nui o te cellulose. ether, penei i te parenga wai, te wa whakatuwhera, te wettability me etahi atu. Inaa, ko te pokey tetahi noa o nga tohu mahi o te cellulose ether, ehara te pokey i te tohu nui mo te mahi matawhānui o te cellulose ether, engari ko te momo me te ihirangi o nga roopu me noho te aro o nga kaihanga moata.

5. Na te mea he nui rawa te aro o nga kaihanga moata ki te pokey, e akiaki ana i etahi umanga whakangao cellulose ether ki te whakanui ake i te pokey na roto i etahi atu rauemi hei whakatutuki i nga whakaritenga a nga kaihanga moata, a ko tenei momo hua anake he tino pokey tino kitea, tona matawhānui. Ko nga mahi e tika ana kia arohia e nga kaiwhakamahi, a, ko te ahua o te pokey teitei i puta mai i te piki ake o te pokey e kore e taea te whakatutuki i te ariā "High viscosity low content" e tumanakohia ana e nga kaihanga moata, engari kaore i te noho. Hei whiriwhiri i te cellulose ether, he mea tino nui i roto i te kumete, me mohio nga umanga moata e whai ana i te kounga teitei me te pumau ki etahi korero kei muri, ka pai tenei ki nga kaihanga ki te whakawhanake i nga hua tino mahi, ki te whakarite i te pumau o te kounga o te hua.
