Ko te nui o te HPMC e whakamahia ana i roto i ngā mahi mahi ka rerekē i runga i te āhuarangi, te pāmahana, te kounga o te paura konupūmā pungarehu o te rohe, te tauira o te paura putty me te "kounga e hiahiatia ana e ngā kiritaki". Ko te tikanga, kei waenga i te 4 kg me te 5 kg. Hei tauira: ko te nuinga o te paura putty i Beijing he 5 kg; ko te nuinga o te paura putty i Guizhou he 5 kg i te raumati me te 4.5 kg i te takurua; he iti noa te nui o te putty i Yunnan, ko te tikanga he 3 kg ki te 4 kg, me ētahi atu.
He aha te matotoru e tika ana mō te hydroxypropyl methylcellulose (HPMC) mō te hanga paura putty?
Ko te utu mō te paura putty he 100,000 yuan te nuinga, ā, he nui ake ngā whakaritenga mō te moata, ā, e 150,000 yuan te utu e hiahiatia ana mō te whakamahinga ngāwari. Heoi anō, ko te mahi nui rawa atu o te HPMC ko te pupuri i te wai, ā, muri iho ko te whakamātotoru. I roto i te paura putty, mena he pai te pupuri i te wai, ā, he iti te matotoru (70,000-80,000), ka taea hoki. Ko te tikanga, ko te teitei ake o te matotoru, ko te pai ake o te pupuri wai whanaunga. Ina neke atu te matotoru i te 100,000, ka pā te matotoru ki te pupuri wai. Kāore e nui rawa atu.
He aha te mahi matua o te whakamahinga o te HPMC ki te paura putty?
I roto i te paura putty, e toru ngā mahi a te HPMC, arā, te whakamātotoru, te pupuri wai, me te hanganga.
Te Whakamātotoru: Ka taea te whakamātotoru i te cellulose hei whakairi me te pupuri i te wai kia ōrite ki runga, ki raro, ā, kia kore ai e totohu.
Te pupuri wai: kia āta maroke te paura putty, ā, āwhina i te konupūmā pungarehu kia tauhohe i raro i te mahi a te wai.
Hanganga: He pānga whakahinuhinu tō te cellulose, ā, ka pai te hanganga o te paura putty.
Kāore te HPMC e whai wāhi ki ngā tauhohenga matū, engari he mahi āwhina noa iho. He tauhohenga matū te tāpiri wai ki te paura putty me te whakatakoto ki te pakitara, nā te mea ka puta he matū hou. Ki te tangohia e koe te paura putty i runga i te pakitara mai i te pakitara, ka hurihia kia paura, ka whakamahia anō, kāore e mahi nā te mea kua puta he matū hou (konupūmā kāponāte). Ko ngā wāhanga matua o te paura konupūmā pungarehu ko: he ranunga o Ca(OH)2, CaO me te iti o CaCO3, CaO H2O=Ca(OH)2—Ca(OH)2 CO2=CaCO3↓ H2O Ko te mahi a te konupūmā pungarehu i roto i te CO2 i roto i te wai me te hau I raro i tēnei āhuatanga, ka puta te konupūmā kāponāte, ko te HPMC ia ka pupuri noa i te wai, ka āwhina i te tauhohenga pai ake o te konupūmā pungarehu, ā, kāore e whai wāhi ki tētahi tauhohenga.
