Abũbuwan amfãni da rashin amfani na Calcium-Zinc Stabilizers a cikin Samar da PVC

Babban Amfani

1. Yana da fitattun kariyar muhalli da halaye marasa guba

Calcium-zinc stabilizers ba su ƙunshi ƙarfe masu nauyi kamar gubar da cadmium ba, kuma suna bin ƙa'idodin kare muhalli na duniya kamar EU RoHS da REACH. Ana iya amfani da samfuransa a cikin filayen da ke da manyan buƙatun aminci kamar marufi na abinci da na'urorin likitanci, guje wa haɗarin haɗari na ƙwayoyin cuta na masu daidaita gishirin gubar na gargajiya.

2. Kyakkyawan kwanciyar hankali na thermal

Calcium-zinc stabilizers na iya ɗaukar HCl da kyau da aka saki yayin sarrafa PVC ta hanyar tasirin haɗin gwiwar hydrotalcite (bimetallic hydroxide) da polyols, don haka yana hana halayen lalacewa. Gwaje-gwaje sun nuna cewa lokacin kwanciyar hankali na thermal na high quality calcium-zinc stabilizers na iya kaiwa sama da mintuna 100, kuma yanayin juriya na wasu nau'ikan yana da 15 ℃ sama da na gishirin gubar na gargajiya.

3. A aiki saukaka ne na ƙwarai

Foda nau'in nau'in foda (lissafin fiye da 80%) ya dace don daidaitaccen ma'auni da haɗuwa, kuma yana sauƙaƙe tsarin samarwa. A halin yanzu, halayen lubrication na ciki na iya rage ƙarin adadin kayan shafawa na waje da rage haɗarin hazo. Misali, ƙwararrun ma'auni na calcium-zinc na iya kula da ruwa na narkewa a cikin sarrafa bututu mai ƙarfi, kuma saman saman samfuran ya fi na tsarin gishirin gubar.

4. Inganta daidaiton kayan aiki

Wasu gyare-gyare suna haɓaka ƙarfin haɗin kai tsakanin resin da filler ta hanyar fasahar haɗin gwiwa, suna ba da izinin ƙara ƙarin kayan aiki marasa tsada kamar calcium carbonate, wanda zai iya rage farashin kayan da kashi 5-10%.

Iyakokin aikace-aikace

1. Tagar fasahar sarrafawa tana da kunkuntar

Tsarin calcium-zinc yana da matukar damuwa ga zafin jiki. Idan zafin jiki na sarrafawa ya canza da fiye da 5 ℃, yana iya haifar da canza launin fari (rawaya) ko kona zinc. Misali, samar da tsattsauran bututun PVC na buƙatar kulawa mai tsauri na saurin dunƙulewa da mutuƙar zafin kai, kuma tsarin zagayowar zagayowar ya fi na gishirin gubar tsawon kashi 30%.

2. Rashin isasshen kwanciyar hankali na dogon lokaci

Wasu ƙananan samfurori suna da sauƙi don canza launin a cikin mataki na gaba lokacin da aka fallasa su zuwa hasken ultraviolet ko zafi mai zafi, kuma kayan anti-tsufa na samfuran sun fi na tsarin organotin rauni. Nazarin ya nuna cewa ƙari na β-diketone additives zai iya inganta wannan lahani, amma farashin yana ƙaruwa da fiye da 20%.

3. Babban dogaro akan man shafawa

Don daidaita saurin filastik, ƙarin kayan shafawa na waje kamar kakin zuma mai oxidized da Pe Wax bukatar a kara. Yin amfani da yawa na iya haifar da ajiyar carbon a cikin ƙira, kuma za'a iya taƙaita sake zagayowar tsaftace gyare-gyare zuwa kashi 50% na tsarin gishirin gubar. Misali, lokacin sarrafa samfuran gaskiya, yakamata a zaɓi na'urori na musamman na calcium-zinc stabilizers don hana hazo.

4. Ciniki-kashe tsakanin Kudin da Ayyuka

Farashin na'urori masu ƙarfi na calcium-zinc (kamar waɗanda ke ɗauke da simintin ƙwayoyin microcrystalline 4A) ya kai yuan 22 a kowace kilogram, wanda ya ninka na gishirin gubar sau 3 zuwa 5. Ko da yake ana iya rage farashin ta hanyar ƙara adadin filler, ana iya yin hadaya da kayan aikin injiniya na samfur.

Ci gaban Outlook

A halin yanzu, na'urorin tabbatar da calcium-zinc sun mamaye kashi 35% na kason kasuwar hada-hadar kudi ta PVC na duniya, kuma girman kasuwar cikin gida ya zarce yuan biliyan 1.2. Abubuwan da ke faruwa a nan gaba sun haɗa da: haɓaka fasaha na nano-hydrotalcite mai haɗawa don haɓaka kwanciyar hankali na thermal, inganta tsarin haɗin gwiwa na polyols da esters phosphite don tsawaita tsarin tsabtace gyare-gyare, da rage farashin sabbin abubuwan ƙari kamar nanowires na azurfa ta hanyar daskarewa. Tare da ƙarfafa manufofin kariyar muhalli, ƙimar shigar da wannan abu a fagage kamar bayanan gine-gine da catheters na likita zai ci gaba da ƙaruwa.
