    1. mmanu ime na mpụga:

    HPMC nwere ike rụọ ọrụ dị ka onye na-agba mmanụ na nhazi PVC. Ọ na-enyere aka melite arụmọrụ nke ogige PVC ma na-ebelata esemokwu n'oge extrusion na ịkpụzi usoro. HPMC nwere ike na-arụ ọrụ dị ka ma n'ime ma na mpụga mmanu, na-eme ka mkpokọta processability nke PVC ihe.

    2. Nhazi emelitere:

    Mgbakwunye nke HPMC na ogige PVC na resin nwere ike ịkwalite usoro nhazi ha, na-eme ka ọ dịkwuo mfe ịmepụta na ịkpụzi ngwaahịa PVC. Nke a dị mkpa karịsịa na ụlọ ọrụ ebe ịkpụzi na extrusion ziri ezi dị oke mkpa.

    Enwere ike iji HPMC na extrusion nke profaịlụ PVC, ọkpọkọ, na ngwaahịa ndị ọzọ, ebe ọ na-enyere aka ịkwalite akụrụngwa na-eruba na ibelata oriri ike.

    2. PVC injection ịkpụzi:

    Ịkpụzi injection nke ngwaahịa PVC, dị ka ihe nrụnye na akụrụngwa, nwere ike irite uru site na iji HPMC iji gbochie ịrapara na melite ntọhapụ ebu.

    3. Ngwakọta PVC:

    Na PVC compounding, ebe dị iche iche mgbakwunye na fillers na-ejikọta na PVC resin, HPMC nwere ike na-eje ozi dị ka a nhazi enyemaka ikwado edo dispersion na melite processability.

    4. PVC kalenda:

    HPMC nwere ike na-arụrụ ọrụ na PVC calending Filiks maka mmepụta nke Ibé akwụkwọ na fim, ebe ọ na-enyere aka belata esemokwu ma melite àgwà nke ikpeazụ ngwaahịa.

    Uru nke iji PVC ọkwa HPMC:
