Ibiranga ikoreshwa rya hydroxypropyl methylcellulose mu nganda za PVC

Intangiriro kuri Hydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl methylcellulose, bakunze kwita HPMC, ni selile ikomoka kuri selile isanzwe.Ikoreshwa cyane mubwubatsi, imiti, ibiryo nizindi nganda, cyane cyane munganda za PVC.Ifumbire ni ifu yera, idafite impumuro nziza hamwe namazi meza yo gukama hamwe nibintu bitandukanye byumubiri na chimique bituma bikenerwa mubikorwa bitandukanye.

Kunoza imiterere ya rheologiya:

Imwe mumisanzu ikomeye ya HPMC mubikorwa bya PVC ningaruka zayo kumiterere ya rheologiya.Ikora nka rheologiya ihindura, igira ingaruka no gutembera kwa PVC mugihe cyo gutunganya.Ibi ni ingenzi cyane muburyo bwo gukuramo no gutera inshinge.

Kongera imbaraga za PVC:

HPMC izwiho ubushobozi bwo kunoza imiterere, mu nganda za PVC bivuze guhuza neza hagati ya PVC nibindi bikoresho.Ibi ni iby'igiciro cyinshi mubikorwa byo gukora PVC hamwe no kuvanga, aho gukomera gukomeye hagati yingirakamaro mubikorwa byiza.

Kubika amazi no gutuza:

Mubisobanuro bya PVC, nibyingenzi kubungabunga amazi murwego runaka mugihe cyo gutunganya.HPMC ikora nk'igikoresho cyo kubika amazi, irinda gukama imburagihe kandi ikanatanga urugero rw'amazi ahoraho.Ibi nibyingenzi byingenzi mubisabwa aho hydratiya yimiterere ya PVC igira ingaruka kumiterere yibicuruzwa byanyuma.

Kugenzura porogaramu zisohoka:

HPMC ikoreshwa kenshi hamwe na PVC mugutegekwa kurekura.Ibi birasanzwe mubikorwa byubuhinzi aho sisitemu ya PVC ikoreshwa mukugenzura irekurwa ryifumbire cyangwa imiti yica udukoko.Ibintu birambye kandi byateganijwe biranga HPMC byoroshya kurekurwa.

Ingaruka kumiterere ya firime ya PVC:

Ongeraho HPMC mubisobanuro bya PVC birashobora kugira ingaruka kumiterere ya firime yavuyemo.Ibi birimo ibintu nko guhinduka, gukorera mu mucyo n'imbaraga za mashini.Ukurikije ibisabwa byihariye byibicuruzwa byarangiye, HPMC irashobora guhindurwa kugirango itange firime ya PVC imitungo yifuza.

Ubushyuhe hamwe no kurwanya UV:

Ibicuruzwa bya PVC birasabwa kenshi kwihanganira ibidukikije.HPMC itezimbere imikorere rusange ya PVC mukongera imbaraga zo guhangana nubushyuhe nubushyuhe bwa UV.Ibi ni ingenzi cyane mubikorwa byo hanze aho PVC ihura nizuba ryikirere nikirere.

Guhambira no guhagarika abakozi:

HPMC ikoreshwa nka binder muburyo bwa PVC, ifasha muguhuza ibice no guteza imbere kwibumbira hamwe.Byongeye kandi, ikora nkumukozi uhagarika, ikabuza ibice gutuza no kwemeza gukwirakwiza kimwe muri materix ya PVC.

Hindura igipimo cya resept:

Imikorere ya HPMC mubikorwa bya PVC akenshi biterwa numubare wimikorere.Kuringaniza kwibanda kwa HPMC hamwe nibindi byongeweho hamwe na PVC resin ningirakamaro kugirango ugere kubintu byifuzwa byibicuruzwa byanyuma.

Guhuza nibindi byongeweho:

Guhuza nibindi byongeweho, plasitike na stabilisateur ni ikintu cyingenzi cyo kwinjiza HPMC muburyo bwa PVC.Kugenzura niba HPMC ikorana hamwe nibindi bice nibyingenzi kugirango ikomeze imikorere rusange hamwe niterambere ryimikorere ya PVC.

Uburyo bwo gutunganya:

Imiterere yo gutunganya, harimo ubushyuhe nigitutu mugihe cyo gukuramo cyangwa kubumba, birashobora kugira ingaruka kumikorere ya HPMC.Gusobanukirwa nubushyuhe bwumuriro nibisabwa bya HPMC nibyingenzi mugutezimbere ibikorwa byinganda.

mu gusoza

Muri make, hydroxypropyl methylcellulose igira uruhare runini mu nganda za PVC, ifasha kunoza imiterere yo gutunganya, gufatira hamwe, gufata amazi no gukora muri rusange ibicuruzwa bishingiye kuri PVC.Mugihe inganda zikomeje gutera imbere, imitungo yihariye ya HPMC irashobora gukomeza gukoreshwa mubikorwa bishya no gutera imbere mubuhanga bwa PVC.Nkuko abashakashatsi nababikora binjira cyane mubufatanye hagati ya HPMC na PVC, amahirwe yo gushiraho no kuzamura ibicuruzwa bya PVC ni menshi.
