Tikanga tautuhi māmā o te hydroxypropyl methylcellulose

He whānuitia te whakamahinga o te cellulose i roto i te matū hinu, te rongoā, te hanga pepa, te whakapaipai, ngā rauemi hanga, me ētahi atu. He tino maha ngā whakamahinga o tēnei tāpiringa, ā, he rerekē ngā whakaritenga mahi mō ngā hua cellulose i ia whakamahinga.

Ko te kaupapa matua o tēnei tuhinga ko te whakamahinga me te tikanga tautuhi kounga o te HPMC (hydroxypropyl methylcellulose ether), he momo cellulose e whakamahia whānuitia ana i roto i te paura putty noa.

Ka whakamahia e te HPMC te miro kua whakatikatikaina hei rauemi mata matua. He pai te mahi, he utu nui, ā, he ātete pai ki te kawakore. He pai mō te putty ātete-wai noa me te moata polymer i hangaia mai i te sima, te konupūmā raima me ētahi atu rauemi kawakore kaha. Ko te awhe matotoru he 40,000-200,000S.

Anei ētahi tikanga hei whakamātautau i te kounga o te hydroxypropyl methylcellulose kua whakarāpopototia e Xiaobian māu. Haere mai ki te ako me Xiaobian~

1. Te mā:

Heoi anō, ko te mea nui hei whakatau i te kounga o te hydroxypropyl methylcellulose, ehara i te mea ko te mā anake. Ka tāpirihia e ētahi kaihanga he mea whakama ki te tukanga whakaputa, engari i tēnei wā, kāore e taea te aromatawai i te kounga, engari he tino pai te mā o te hydroxypropyl methylcellulose kounga teitei.

2. Te ātaahua:

Ko te matotoru o te hydroxypropyl methylcellulose he 80 mata, 100 mata me te 120 mata. He tino matotoru te matotoru o ngā matūriki, ā, he pai hoki te wairewa me te pupuri wai. He hydroxypropyl methylcellulose kounga teitei tēnei.

3. Te tuku mārama:

Tāpirihia te hydroxypropyl methylcellulose ki roto i te wai, ka whakarewahia ki te wai mō tētahi wā hei tirotiro i te matotoru me te mārama. Kia oti te hanga o te wairewa, tirohia tōna kaha ki te whakawhiti mārama, ki te pai ake te kaha ki te whakawhiti mārama, ka nui ake te kore e rewa me te parakore.

4. Te taumaha motuhake:

Ka nui ake te taumaha motuhake, ka pai ake; nā te mea ka taumaha ake te taumaha motuhake, ka nui ake te ihirangi o te hydroxypropyl methyl i roto, ka pai ake te pupuri wai.
