Polymer Polymer Hydroxyppypylthylcelllose maka ciment dabere na ciment

Hydroxypyl Methylcelllose (HPMC) bụ polyr polymer ekere eke nke na-eji n'ọtụtụ ụlọ ọrụ owuwu dị ka ihe mgbakwunye ciment. Enwere ike iji ya dị ka onye na-ahụ maka njigide mmiri, Trimener, na ihe mkpuchi iji melite arụmọrụ nke ciment ciment.

HPMC bụ semi-synler, nke mmiri na-agbanye site na cellususe. A na - enweta ya site na sellulose site na usoro mgbanwe kemịkalụ nke na - agụnye mgbakwunye nke hydropyyl na methyl. Ndozi a na - arụpụta polymen nwere mmiri dị mma, nkwụsi ike ọkụ, na kemịkalụ.

Ojiji nke HPMC na usoro plasta apịtị na-enye ọtụtụ uru dị ka:

1. Ọrụ dị mma: HPMC na-arụ ọrụ dị ka ihe omimi Rhiolog nke na-eme ka ọrụ na ngwa Njirimara nke plasta. Ọ na - eme ka ndọnye nchekwa, cohesion, na ịgbasa nke plasta ahụ, na - enye ya ohere itinye ya n'ọrụ n'ụzọ dị mfe itinye ya na mkpụrụ.
2. Ndozi mmiri na-eme ka mmiri sie ike: HPMC nwere ike ịmịkọta ma jigide nnukwu mmiri, nke na-enyere aka igbochi plasta ahụ iji kpochapụ ngwa ngwa. Ngwongwo a na-emekwa ka nke a na-eji plasta na-agbanwe agbanwe na ọrụ ọrụ ogologo oge, ọbụlagodi na ọnọdụ ọkụ na ala.
3. Mmụba na Adhesion: HPMC na-etolite ihe nkiri gburugburu ciment, nke na-eme ka njikọta ha na ngwakọta ha na-eme ka ọ dị. Ngwongwo a na - enyere aka na plasta ahụ na - adịghị edozi ma ọ bụ hapụ ma ọ bụ kewapụ na mkpụrụ.
4. Belata Cracking: HPMC na-eme ka ike tensile na nnweta nke plasta, na-ebelata ohere nke ịgbagọ n'ihi mmụba.
5. Oge dị anya: HPMC na-enye akwa ahụ nwere mmiri na-eguzogide mmiri na kemịkasị kemịkalụ, na-eme ka ọ na-adịgide adịgide ma na-eguzogide ihu igwe na-eguzogide.

Na mgbakwunye na uru ndị a, HPMC bụkwa ihe na-adịgide adịgide na ọnọdụ metụtara gburugburu ebe obibi nwere ike inye aka belata mmetụta gburugburu ebe obibi. Ọ bụ ihe na-adịghị egbu egbu, biodegraddable, ọ hapụghị ihe na-emerụ ahụ na gburugburu ebe obibi.

Iji jiri HPMC na ciment ciment, a na-agbakwunye ya na ngwakọta akọrọ ciment na ájá tupu mgbakwunye nke mmiri. Usoro a tụrụ aro nke HPMC dị iche iche dabere na ngwa ụfọdụ na akụrụngwa achọrọ nke plasta. N'ozuzu, usoro nke 0.2% ruo 0.5% nke HPMC dabere na mkpokọta oke ciment na ájá.

HPMC bụ ihe dịgasị iche na nke dị irè nke nwere ike imeziwanye arụmọrụ nke ciment ciment. Ebumnuche ya sitere n'okike, nkwado nke Eco-Eco-Eco na-eme ka ọ bụrụ nhọrọ mara mma maka ndị enyemaka, ụkpụrụ ụlọ, na ndị nwe ụlọ na-akpalite omume ụlọ na-akpalite.
