Polyvinyl chloride (PVC) mkpuchi ntụ ntụ

Polyvinyl chloride (PVC) bụ polymer amorphous nwere obere kristal na-ezughị ezu. Ọtụtụ PVC Ngwaahịa resin nwere molekul dị n'etiti 50,000 na 120,000. Ọ bụ ezie na ịdị arọ molekụla dị elu PVC resins nwere ihe anụ ahụ ka mma, ịdị arọ molekụla dị ala PVC resins na ala gbazee viscosity na nro okpomọkụ dabara adaba dị ka ihe maka thermoplastic ntụ ntụ agba.

PVC n'onwe ya bụ ihe siri ike na enweghị ike iji ya dị ka ihe agba agba naanị. Mgbe ị na-eme ihe mkpuchi, ọ dị mkpa ka a gbakwunye ihe ụfọdụ nke plasticizer iji dozie mgbanwe nke PVC. N'otu oge ahụ, ịgbakwụnye plasticizers na-ebelatakwa ike nkwụsi ike, modulus na ike nke ihe. Ịhọrọ ụdị kwesịrị ekwesị na ọnụ ọgụgụ nke plasticizer nwere ike nweta nguzozi achọrọ n'etiti mgbanwe ihe na ike siri ike.

Maka zuru ezu PVC ntụ ntụ agba usoro, stabilizers bụkwa akụkụ dị mkpa. Iji dozie thermal kwụsie ike nke PVC, ngwakọta salts nke calcium na zinc na ezi thermal kwụsie ike, barium na cademeputala ncha mium, tin mercaptan, ihe nrụpụta dibutyltin, ogige epoxy, wdg. Ọ bụ ezie na ndị na-ahụ maka ndu ndú nwere nkwụsi ike ọkụ dị mma, ewepụla ha n'ahịa n'ihi ihe kpatara gburugburu ebe obibi.

2. Ihe mkpuchi ahụ anaghị eguzogide ọgwụ hydrocarbons aromatic, esters, ketones, na ihe mgbaze chlorinated, wdg.

Polyamide (nylon) ntụ ntụ mkpuchi

Polyamide resin, nke a na-akpọkarị naịlọn, bụ resin thermoplastic a na-ejikarị eme ihe. Nylon nwere ezigbo ihe njiri mara nke ọma, isi ike dị elu, yana nguzogide iyi dị egwu. Ọnụ ọgụgụ esemokwu na-agbanwe agbanwe na static nke mkpuchi nylon dị ntakịrị, ma ha nwere mmanu. Ya mere, a na-eji ha eme ihe na-eji ígwè ọrụ textile, gears, valves, wdg. Nylon ntụ ntụ mkpuchi nwere ezigbo mmanu, obere mkpọtụ, mgbanwe dị mma, mma mmachi, nguzogide kemịkalụ, na ihe mgbaze. Enwere ike iji ha dị ka ihe mkpuchi na-eguzogide ọgwụ na mmanu mmanu iji dochie ọla kọpa, aluminom, cadmium, ígwè, wdg The njupụta nke nylon mkpuchi film bụ nanị 1/7 nke ọla kọpa, ma ya eyi iguzogide bụ ugboro asatọ nke ọla kọpa.

Ihe mkpuchi ntụ ntụ nylon adịghị egbu egbu, enweghị isi, na enweghị ụtọ. N'ikwekọ na eziokwu ahụ bụ na ha anaghị anabata mwakpo fungal ma ọ bụ na-akwalite uto nje, a na-etinye ha n'ọrụ nke ọma na ụlọ ọrụ na-edozi nri na-ekpuchi ihe ndị dị na igwe na usoro pipeline ma ọ bụ na-ekpuchi elu ndị na-abanye na nri. N'ihi oke mmiri na mmiri nnu na-eguzogide ya, a na-ejikarị ya eme ihe maka mkpuchi akụkụ igwe ịsa akwa, wdg.

Ebe dị mkpa dị mkpa nke mkpuchi mkpuchi nylon ntụ ntụ bụ ịkwanye ụdị aka dị iche iche, ọ bụghị nanị n'ihi na ha nwere njirimara dị mkpa dị ka nkwụsị na-eguzogide ọgwụ, kamakwa n'ihi na obere okpomọkụ ha dị ala na-eme ka aka ahụ dị nro. Nke a na-eme ka ihe ndị a dị mma maka mkpuchi ngwá ọrụ mkpuchi, ọnụ ụzọ, na wiil ndị na-eduzi.

E jiri ya tụnyere ihe mkpuchi ndị ọzọ, ihe nkiri mkpuchi nylon nwere nguzogide kemịkalụ na-adịghị mma na adịghị mma maka ojiji na gburugburu kemịkalụ dị ka acids na alkalis. Ya mere, a na-agbakwunye ụfọdụ resin epoxy dị ka ndị na-agbanwe agbanwe, nke na-enweghị ike imeziwanye nguzogide corrosion nke mkpuchi naịlọn kamakwa ọ na-eme ka ike njikọ dị n'etiti ihe nkiri mkpuchi na mkpụrụ ígwè. Nylon ntụ ntụ nwere oke nnabata mmiri na-enwe ike iru mmiri n'oge ewu na nchekwa. Ya mere, ọ dị mkpa ka ịchekwa ya n'okpuru ọnọdụ mkpuchi ma ghara iji ya mee ihe ruo ogologo oge n'okpuru ọnọdụ iru mmiri na ọkụ. Akụkụ ọzọ ị ga-amata bụ na oge plasticizing nke nylon ntụ ntụ dị mkpụmkpụ, na ọbụna ihe nkiri mkpuchi nke na-adịghị mkpa plasticizing nwere ike nweta mmetụta a chọrọ, nke bụ ihe pụrụ iche nke ntụ ntụ nylon.

Polyvinylidene fluoride (PVDF) agba ntụ ntụ

Ihe mkpuchi na-eguzogide ihu igwe kachasị mma na agba ntụ ntụ thermoplastic bụ mkpuchi ntụ ntụ polyvinylidene fluoride (PVDF). Dị ka ihe nnọchianya nke ethylene polima na-eguzogide ihu igwe, PVDF nwere ezigbo nrụpụta ọrụ na nguzogide mmetụta, nkwụsi ike dị mma nke ukwuu, mgbanwe mgbanwe na ike siri ike, ma nwee ike iguzogide ọtụtụ kemịkalụ na-emebi emebi dị ka acid, alkalis, na oxidants siri ike. Ọzọkwa, ọ bụ ihe a na-adịghị ahụkebe na kemịkalụ kemịkalụ a na-ejikarị eme ihe na ụlọ ọrụ mkpuchi, nke bụ n'ihi njikọ FC nke dị na PVDF. N'otu oge ahụ, PVDF na-emezukwa ihe FDA chọrọ ma nwee ike iji ya mee ihe na nhazi nri ma nwee ike ịbanye na nri.

N'ihi nnukwu mgbaze viscosity ya, PVDF na-adịkarị mfe na pinholes na nchikota ígwè na-adịghị mma na mkpuchi ihe nkiri dị mkpa, ọnụahịa ihe dị oke elu. Ya mere, n'ọtụtụ ọnọdụ, a naghị eji ya dị ka naanị ihe ndabere maka mkpuchi ntụ ntụ. N'ozuzu, ihe dị ka 30% nke resin acrylic ka a na-agbakwunye iji melite njirimara ndị a. Ọ bụrụ na ọdịnaya nke resin acrylic dị oke elu, ọ ga-emetụta iguzogide ihu igwe nke ihe nkiri mkpuchi.

The gloss nke PVDF mkpuchi film bụ dịtụ ala, n'ozuzu gburugburu 30± 5%, nke na-amachi ya ngwa na elu mma. Ka ọ dị ugbu a, a na-ejikarị ya dị ka mkpuchi ụlọ maka nnukwu ụlọ, na-etinye ya n'elu ụlọ elu, mgbidi, na windo aluminom extruded, na-eguzogide ihu igwe dị oke mma.
