1. He aha ngā tohu hangarau matua o te hydroxypropyl methyl cellulose (HPMC)?
Ko te nui me te matotoru o te HPMC Hydroxypropyl, he maha ngā kaiwhakamahi e āwangawanga ana mō ēnei tohu e rua. Ko te pupuri wai he pai ake mō te hunga he nui te ihirangi hydroxypropyl. Ko te matotoru teitei, ko te pupuri wai, he pai ake (kaua i te tino), ā, ko te matotoru teitei, he pai ake te whakamahi i roto i te moata sima.
2. He aha te mahi matua o te whakamahinga o te HPMC ki te putty pakitara?
I roto i te putty pakitara, e toru ngā mahi a te HPMC: te whakamātotoru, te pupuri wai me te hanga.
Te Whakamātotoru: Ka taea te whakamātotoru i te cellulose hei whakairi me te pupuri i te ōrite o te wairewa, ā, hei ārai hoki i te totohu. Te pupuri wai: kia āta maroke te putty pakitara, ā, kia āwhina i te konupūmā hina ki te tauhohe i raro i te mahi a te wai. Te Hanganga: He pānga whakahinuhinu te cellulose, ka taea ai te pai o te mahi a te putty pakitara.
3. He hononga tō te maturuturunga iho o te putty pakitara ki te HPMC?
Ko te maturuturunga o te putty pakitara e pā ana ki te kounga o te konupūmā pungarehu, engari kāore ki te HPMC. Mena kāore i te tika te nui o te konupūmā o te konupūmā pungarehu me te ōwehenga o te CaO me te Ca(OH)2 i roto i te konupūmā pungarehu, ka ngaro te paura. Mena he pānga ki te HPMC, ko te iti o te pupuri wai o te HPMC ka ngaro hoki te paura.
4. E hia te nui o te hydroxypropyl methyl cellulose (HPMC) i roto i te putty pakitara?
Ko te nui o te HPMC e whakamahia ana i roto i ngā tono tūturu ka rerekē i runga i te āhuarangi, te pāmahana, te kounga o te konupūmā pungarehu o te rohe, te tauira o te putty pakitara, me te "kounga e hiahiatia ana e ngā kiritaki". I te nuinga o te wā, i waenga i te 4 kg me te 5 kg. Hei tauira: Ko te putty pakitara o Beijing he 5 kg te nuinga; ko Guizhou he 5 kg te nuinga i te raumati me te 4.5 kg i te takurua; he iti noa a Yunnan, he 3 kg ki te 4 kg te nuinga, me ētahi atu.
5. He aha te matotoru tika o te hydroxypropyl methyl cellulose (HPMC)?
Ko te putty pakitara he 100,000 te nuinga, engari he nui ake te uaua o te moata, ā, e 150,000 te roa hei mahi. Heoi anō, ko te mahi nui a te HPMC ko te pupuri wai, ā, muri iho ko te whakamātotoru. I roto i te putty pakitara, mena he pai te pupuri wai, he iti iho te matotoru (70-80,000), ka taea hoki, he pono, he teitei ake te matotoru, ā, he pai ake te pupuri wai. Ina neke atu te matotoru i te 100,000, kāore he pānga o te matotoru ki te pupuri wai.
6. Me pēhea te whiriwhiri i te hydroxypropyl methylcellulose (HPMC) tika mō ngā kaupapa rerekē?
Te whakamahinga o te putty pakitara: he iti ake te hiahia, ko te matotoru he 100,000, he rawaka, ko te mea nui kia pai ake te pupuri i te wai. Te whakamahinga o te moata: he nui ake ngā hiahia, he matotoru teitei, he pai ake i te 150,000, te whakamahinga o te kāpia: he hua tere te memeha, he matotoru teitei.
7. He aha te take e puta ai he mirumiru i te whakamahinga o te HPMC ki te putty pakitara?
E toru ngā mahi a te HPMC i roto i te putty pakitara: te whakamātotoru, te pupuri wai me te hanganga. Kaua e uru ki tētahi tauhohenga. Ngā take mō ngā mirumiru:
(1) He nui rawa te wai e tāpirihia ana.
(2) Kāore te paparanga o raro i maroke, ā, ka waruhia tētahi atu paparanga ki runga, he mea ngāwari hoki te pahuka.
