4. Ngā hua tukatuka kirihou me ngā hua polymer
Ka taea te whakamahi i te HPMC hei hinu whakahinuhinu, hei kaihoko tuku, hei kaiwhakamarara hoki i roto i ngā tauhohenga polymerization:
4.1. Te hanga kirihou PVC, ABS me ētahi atu
Hei whakaū i te whakarewa i roto i te tukanga whakapūhui whakatārewatanga kia ōrite ai te rahi o te matūriki.
4.2. Ngā hua i whakapūpūtia
Whakarato hinu pai, ārai i ngā hua kei piri ki te pokepokea ai, ā, whakapai ake i te āhua o te mata.
5. Ahumahi matū o ia rā (hua taumata ahumahi)
Ahakoa e whakamahia whānuitia ana te HPMC kounga kai, te HPMC kounga rongoā rānei i roto i ngā rongoā ā-waha, i roto i te mara o ngā matū o ia rā, ka whakamahia te HPMC kounga ahumahi mō ngā hua kore-pa, pērā i:
5.1. Hopi horoi kakahu me te wai horoi rihi
Whakarato i te pānga whakamātotoru mārama, whakapai ake i te ōritetanga o te hua, me te whakapai ake i te wheako kaiwhakamahi.
