Kedu ihe bụ njirimara nke calcium zinc stabilizers na gburugburu ebe obibi:
Calcium zinc stabilizers bụ nitric oxide synthases nke nwere calcium zinc organic salts, hypophosphite esters, polyether polyols, antioxidants, na organic solvents. Calcium zinc stabilizers nwere ezigbo ndakọrịta na epoxy resins na thickeners, ezigbo nghọta, na ọ dịghị mfe ịwụsa. A na-eji ha dị obere ma dị mfe iji. Otú ọ dị, ha nwere mwepu nke mmiri mmiri na-adịghị ike, na-ebelata ebe dị nro nke ngwaahịa ahụ, na nchekwa ogologo oge nwere ike ime ka ọkpụkpụ na-eto eto. Ncha ncha calcium zinc mejupụtara steeti siri ike bụ ncha polyether, ncha acid lauric na ncha fatty acid sochiri ya. Njirimara nke calcium zinc stabilizers dị mma wetting, nke na-adịghị ebelata ihe nro nke ngwaahịa PVC siri ike, ọ dịkwa mma maka mmepụta na nhazi nke ọkpọkọ PVC siri ike na profaịlụ PVC. Ngwaahịa emepụtara na nhazi site na teknụzụ microemulsion nwere ike iwepụ ntụpọ ndị ahụ e kwuru n'elu.
Anyị na-elekwasị anya n'akụkụ abụọ iji mee mgbanwe: iji meziwanye agba na mmalite, a na-agbakwunye ncha zinc zuru oke, a na-ejikwa antioxidants na-emeso zinc chloride na-adịghị emerụ ahụ, nke na-aghọ zinc dị elu ma na-ebelata ego. nke ncha zinc agbakwunyere iji gbochie ọkụ zinc.
Ojiji nke ihe nchekwa iji gbanwee usoro agba agba gara aga na-eme ka nchịkọta zinc dị ala, nke a na-ejikarị eme ihe ọ bụghị nanị na ngwaahịa dị nro kamakwa na nkwụsi ike nke okpomọkụ na doo anya nke calcium zinc stabilizers. A na-etinyekwa ya nke ọma na mmepụta na nhazi nke ngwaahịa siri ike, iji mee ka usoro nlekọta calcium / zinc dịkwuo mma ma na-egbochi agba agba mbụ na igbochi zinc ọkụ.
N'ozuzu, nnu nnu na-ejikọta naanị n'elu ihe ndị dị na PVC, na mmetụta ha bụ igbochi njikọ dị n'etiti ihe ndị dị na PVC, na-egbu oge plasticization nke ukwuu, na-ebelata esemokwu n'etiti ihe ndị dị na PVC, na ibelata mmetụta ịkpụ n'ime PVC. Ngwá ọrụ mmepụta ihe na-ebu ibu dị ala, na ọnụ ọgụgụ nke nnu ndu ejiri dị elu. Ka akụkụ nke nnu nnu na-esiwanye ike, ka mmetụta nke abụọ na-abawanye. Akwụkwọ ndụ akwụkwọ ndụ ọdịnala na ngwaahịa gburugburu ebe obibi dị ka calcium zinc stabilizers nwere ike electronegativity n'oge usoro plasticization. Otu ndị na-arụ ọrụ ngwa anya nwere ụfọdụ ọrịa nwere isi njikọ subacute nke PVC epoxy resin, na-emepụta njikọ nwere ike njikọ siri ike, nke na-ebelata ma ọ bụ na-ewepụ mmasị nke njikọ ion dị iche iche nke PVC. Nke a bụ oghere mmeghe nke PVC a na-ejikọta ibe ya, na-eme ka ọ dịkwuo mfe maka mgbasa ozi n'èzí. Ọdịdị molekụla nke otu ndị na-arụ ọrụ na-eme ka ọ dịrị PVC mfe ịgbasa. Ókè nke etiti na-eme ka plasticization nke PVC epoxy resin.
