Ko te Hydroxypropyl Methylcellulose hei wehewehe, he hanganga matūriki, he wetekina hoki ngā matūriki o ngā hua i puta mai, he matotoru te āhua, ā, he pai te mahi tukatuka. Heoi, mā te whakamahi i te Hydroxypropyl Methylcellulose anake ka taea te āwhina i te pumau o te kapia. He ngoikore te mahi whānui o te kapia. Mā te whakamahi matūriki o te hydroxypropyl methylcellulose me ētahi momo waipiro polyvinyl ka taea te whakapai ake i te mahi o ngā hua, te whakahaere i te kounga, ā, i te wā kotahi ka taea te whakaiti i te utu. Ko te kaihoko whakamarara te mea matua e awe ana i te āhua matūriki o te kapia polyvinyl chloride. Ko te iti o te kukū mata o te wai o ngā kaihoko whakamarara whānui me te kukū ā-mata ki te monomer Vinyl chloride, ka pai ake te whakamarara o ngā pata VCM. Nō reira, ka iti ake te diameter matūriki o te kapia PVC. Ko te kaha ake o te kaha tiaki o te kaihoko whakamarara, ka tata ake ngā matūriki kapia PVC i puta mai, ā, ka iti ake te porosity. Ā, he uaua ake hoki te whakakotahitanga intergranular, nō reira he ngāwari te hanga kapia.
Hei tauira, i roto i te pūnaha marara matū o te PVA me te HPC, ka teitei ake te taumata waipiro o te PVA, ka nui ake te kukū o te mata o te wairewa, ā, ka kaha ake te kaha tiaki, i te mea he pai te pānga marara o te hydroxypropyl methylcellulose. Nō reira, ko te whakamahi i te PVA me te taumata waipiro teitei hei kaupapa matua.
kaihoko whakamarara, me te whakakotahi i te
tetahi nui o te hydroxypropyl methylcellulose
Hei kaihopu whakamarara mō te whakapūhui whakatārewatanga, he māmā ake te whakarite i te kapia PVC ka taea te whakatutuki i ngā whakaritenga o te āhua o te matūriki. Hei tauira, i roto i te pūnaha whakamararatanga matū o te PVA me te HPC, ka teitei ake te tohu waipiro o te PVA, ka nui ake te kukū o te mata o te wairewa, ā, ka kaha ake te kaha tiaki, i te mea he pai te pānga whakamararatanga o te hydroxypropyl methylcellulose.
