Amakuru

Plasitiki y'insinga n'insinga (izwi nka ibikoresho by'insinga) ni ubwoko bwa polyvinyl chloride, polyolefins, fluoroplastics, n'izindi plastiki (polystyrene, polyester amine, polyamide, polyimide, polyester, n'izindi). Muri zo, polyvinyl chloride, na polyolefins byagize uruhare runini mu bipimo, ibi bikurikira ni intangiriro yo gukoresha inyongera za pulasitiki mu bikoresho bya PVC na polyolefins ndetse n'ingaruka zabyo ku miterere ya pulasitiki.

Plasitike igizwe ahanini na resin y’ubukorikori, ari nayo igena imikorere y’ibanze y’ibikoresho bya pulasitiki. Nyamara ikoreshwa rya resin ryonyine ntirishobora kuzuza ibisabwa byihariye by’insinga n’insinga zitandukanye kandi ibisabwa mu gutunganya, bigomba kongerwa ku bindi bikoresho bya pulasitiki bishobora gukorwamo ibikoresho bitandukanye by’insinga kugira ngo bihuze n’ibikenewe ku isoko.

Ni izihe nkunga zikoreshwa mu gutunganya ibikoresho bya PVC? Muri rusange hari ubwoko bukurikira bw'inyongera:

1, Plastiseri

Plastiseri ni igikoresho cy'ingenzi gikorana muri pulasitiki ya PVC ku nsinga n'insinga. Plastiseriseri kuko ishobora kugira uruhare mu gushonga hagati y'amatsinda y'ibice by'umuraba mu miterere ya molekile ya polyvinyl chloride, intera iri hagati ya molekile za polyvinyl chloride kandi ikagira uruhare mu kuringaniza irekurwa, bityo ishobora kongera imiterere ya plasticity, imiterere yihuta cyane ya fiziki n'iya mashini, no kunoza imikorere y'igikorwa.

2. Umuti urwanya ogisijeni

Mu rwego rwo kwirinda kwangirika no guhuza plastiki mu gihe cyo kuyitunganya no kuyikoresha igihe kirekire bitewe n’imikorere ya ogisijeni, antioxydants zikunze kongerwa kuri plastiki, ibi bikaba ari ingenzi cyane kuri plastiki za PVC zirinda ubushyuhe.

3, Umusemburo w'ibyuzuza

Insinga n'insinga bifite plastiki ya polyvinyl chloride byongeramo icyo bigamije:

Ubwa mbere, kugira ngo ugabanye ikiguzi cy'umusaruro, gira uruhare mu gutanga umusaruro mu buryo bwihuse.

Icya kabiri ni ukunoza imikorere y'ibicuruzwa.

4, Umuti wo gusiga irangi

Ibara rya pulasitiki ya polyvinyl chloride uretse gukora ibicuruzwa bifite amabara meza, rihura n'ibikenewe mu bwiza, ariko kandi rinatuma habaho ubudahangarwa bw'ikirere, rikongera igihe cyo gukora insinga z'itumanaho za pulasitiki n'insinga z'amashanyarazi, zifite amabara atandukanye y'imbere, bityo byoroshya ishyirwaho, ikoreshwa, n'ibungabungwa.

5, Idakoresha umuriro

Imashini igabanya umuriro cyane ku bikoresho bya PVC ni antimony trioxide (Sb2O3), kandi parafini chloride nayo irakora neza, byongeye kandi, hari aluminium hydroxide, magnesium hydroxide, na fosfeti plasticizers.

6. Imashini yo gusiga amavuta

Nubwo ingano y'amavuta ari make, ni ikintu cy'ingenzi cyane kuri pulasitiki ya PVC. Kongeramo amavuta bigabanya ingaruka zo kwangirika no gufatana kwa pulasitiki ku buso bw'icyuma bw'ibikoresho bitunganya, kandi bigabanya ingaruka zo kwangirika no gukurura ubushyuhe hagati y'uduce twa resin na macromolecules ya resin mu gihe resin ishonga nyuma yo gushonga.

7, Uburyo bwo guhindura ibintu mu buryo bwo kuvanga

Polyvinyl chloride ishobora guhindurwa hongewemo polymer modifier kugira ngo inoze imikorere y'ibicuruzwa, kugira ngo yongere urwego rw'ikoreshwa.

Inyongeramusaruro za SILIKE ku nsinga n'insinga——Amahitamo ya mbere kuriibikoresho byo gutunganya insinga n'insinga!

Chengdu Silike Technology Co., Ltd——nk'umuvumbuzi n'umuyobozi mu ikoreshwa rya silikoni mu Bushinwa mu bijyanye na plastiki ya rubber, Silike yibanze ku guhuza silikoni na plastiki mu gihe cy'imyaka irenga 20, ifata iya mbere mu guhuza silikoni na plastiki.

Inyongera zacu za silikoni zishingiye ku maresini atandukanye kugira ngo zihuze neza na thermoplastic, zirimoSILIKE LYSI series silicone masterbatchbinoza cyane urujya n'uruza rw'ibikoresho, inzira yo kubisohora, gukoraho no kubikora ku buso bunyerera, kandi bigakora ingaruka nziza hamwe n'ibikoresho bigabanya umuriro.

Bikoreshwa cyane nk'uburyo bwoinyongeramusaruro nziza mu nsinga za LSZH/HFFR n'insinga, silane crossing ihuza imvange za XLPE, insinga za TPE, umwotsi muke n'imvange za COF nke za PVC.

Ugereranije n'uburemere busanzwe buri hasi bwa molekileInyongera za silikoni/Siloxane, nk'amavuta ya Silicone, amavuta ya Silicone, cyangwa ubundi buryo bwo gutunganya, uruhererekane rwa SILIKE Silicone Masterbatch LYSI rwitezweho gutanga inyungu nziza nkuko bikurikira:

1.Komeza ibibazo byo gutunganya: kunoza cyane uburyo ibikoresho bigenda, kuzuza/kurekura ifu, kugabanya gucika kw'imigozi, kunoza uburyo bwo gusohora, no kugabanya amatembabuzi.

2.Ongera imiterere y'ubuso: Nk'ukugabanya COF, kunoza ubudahangarwa bw'imitsi no gushwanyagurika, no kurushaho kunyerera no kumva neza intoki…

3. Gukwirakwiza vuba ATH/MDH igabanya umuriro.

4.Ingaruka zo gukumira umuriro zishingiye ku buryo buhuriweho.

Hindura ibikoresho byawe by'insinga n'insinga bibungabunge ibidukikije, bitekanye kandi bikomere kugira ngo bikore neza ku iherezo.

Hasi hari agatabo k'ibicuruzwa byaInyongeramusaruro za SILIKE ku nsinga n'insinga, ushobora kureba, niba ukeneye ubufasha bwo gutunganya insinga, SILIKE iragushimiye!
