Ko te Hydroxypropyl methylcellulose, e mohiotia ana ko HPMC, he etera cellulose nonionic i riro mai i te miro para parakore, he rauemi polymer taiao, na roto i te raupapa o nga tukanga matū. He paura ma, he paku kowhai ranei, he ngawari te rewa ki te wai. Me korero tatou mo te tikanga whakakore o te hydroxypropyl methylcellulose.
1. Ko te Hydroxypropyl methylcellulose te nuinga ka whakamahia hei taapiri mo te paura putty, moata me te kopa. Ka taapirihia ki te kumete ciment, ka taea te whakamahi hei kaihoko pupuri wai me te aukati ki te whakanui ake i te pupuhi; tāpiri ki te paura putty me te kāpia, ka taea te whakamahi hei here. Hei whakapai ake i te horahanga me te whakaroa i te wa mahi, ka tango matou i te Qingquan Cellulose hei tauira hei whakamarama i te tikanga whakakorenga o te hydroxypropyl methylcellulose.
2. Ko te hydroxypropyl methylcellulose te tuatahi ka whakaohokia, ka marara ki te wai wera, katahi ka tapirihia ki te wai matao, ka oho me te whakamatao kia memeha;
Ko te tikanga: tangohia te 1/5-1/3 o te nui o te wai wera, whakaohokia kia tino tetere te hua kua tapiritia, katahi ka tapirihia te toenga o te wai wera, he wai matao, he wai hukapapa ranei, ka whakaoho kia te pāmahana e tika ana (10°C ) kia rewa katoa.
3. tikanga makuku whakarewa organic:
Horoihia te hydroxypropyl methylcellulose ki roto i te whakarewa pararopi, whakamakuku ranei ki te whakarewa pararopi, katahi ka taapirihia he wai matao kia memeha pai. Ko te whakarewa pararopi ka taea te ethanol, ethylene glycol, etc.
4. Mena ka tupu te whakahiato, te takai ranei i te wa e memeha ana, na te mea he iti rawa te whakakorikori, he taapiri tika ranei te tauira noa ki te wai matao. I tenei wa, hohoro te whakaoho.
5. Mena ka puta nga mirumiru i te wa e whakakorehia ana, ka taea te waiho mo te 2-12 haora (ko te waa motuhake ka whakawhirinaki ki te rite o te otinga) ka nekehia ranei ma te whakakore, te pehanga, me etahi atu, me te taapiri ranei i te nui o te kaihoko whakakino.
Whakatupato
Ko te Hydroxypropyl methylcellulose kua wehea ki nga momo puhoi-whakarewa me nga momo whakamohoatanga inamata. Ko te hydroxypropyl methylcellulose tere ka taea te rewa tika ki te wai matao.
