Pur cyangwa PVC: Hitamo ibikoresho bikwiye

Iyo ushakisha insinga nziza ninsinga, guhitamo ibikoresho byo gusiga uburenganzira ni ngombwa. Umushinga wo hanze ufite imirimo itandukanye kugirango habeho iramba, umutekano n'imikorere ya kabili cyangwa insinga. Ntibisanzwe ko ugomba guhitamo hagati ya Polurethane (Pur) naPolyvinyl chloride (PVC). Muri iki kiganiro, uziga kubyerekeye itandukaniro ryimikorere hagati yibikoresho byombi na porogaramu buri kintu gikwiranye neza.

Imiterere n'imikorere mikorere ninsinga

Icyuma (nanone cyitwa umugozi wo hanze cyangwa sheath) nigice cyintambwe cyangwa insinga kandi ikoreshwa ukoresheje bumwe muburyo buke. UMWura urinda abayobora invundo n'ibindi bice by'imiterere biva mu bintu byo hanze nko gushyuha, ubukonje, butose cyangwa imiti n'imashini. Irashobora kandi gukosora imiterere nuburyo bwumuryango uhagaze, kimwe nigice kikingira (niba gihari), bityo kugabanya kwivanga hamwe na CableRonagnetic Contabister (EMC). Ibi ni ngombwa kwemeza kohereza imbaraga, ibimenyetso, cyangwa amakuru mumurongo cyangwa insinga. Gukubita kandi bigira uruhare runini mugutura insinga ninsinga.

Guhitamo ibintu byiza cyane cyane ni ngombwa kugirango ugena umugozi mwiza kuri buri porogaramu. Kubwibyo, ni ngombwa kumenya neza intego umugozi cyangwa insinga bigomba gukora nibisabwa bigomba guhura.

Ibikoresho bisanzwe

Polyurethane (Pur) na Polyvinyl chloride (PVC) nibikoresho bibiri bikoreshwa cyane kumigozi ninsinga. Mubyuka, nta tandukaniro riri hagati yibi bikoresho, ariko erekana ibintu bitandukanye bituma bikwiranye na porogaramu zitandukanye. Byongeye kandi, ibindi bikoresho byinshi birashobora gukoreshwa nkibikoresho byo kumenagura, harimo na rubber yubucuruzi, elastoplamest theicosti (tpe), nibice byihariye bya plastiki. Ariko, kubera ko bidakunze kugaragara kurenza Pur na PVC, tuzagereranya gusa ibi byombi mugihe kizaza.

Pur - Ikintu cyingenzi

Polyurethane (cyangwa Pur) bivuga itsinda rya plastike ryateye imbere mu mpera za 1930. Ikozwe mubikorwa bya shimi bita kongeramo polymerisation. Ibikoresho fatizo mubisanzwe peteroli, ariko ibikoresho byibimera nkibirayi, ibigori cyangwa isukari cyangwa isukari cyangwa isukari birashobora kandi gukoreshwa mubikorwa byayo. Polyurethane ni elastomer ya thermoplamer. Ibi bivuze ko guhinduka mugihe ushyushye, ariko urashobora gusubira muburyo bwabo bwambere mugihe ashyushye.

Polyurethane ifite cyane cyane imitungo. Ibikoresho bifite imbaraga nziza zo kurwanya, gutema kurwanya no kurwanya amarira, kandi birahinduka byoroshye cyane ndetse no mubushyuhe buke. Ibi bituma Purly bikwiranye nibisabwa bisaba ibishoboka byose kandi byunamiwe ibisabwa, nkibihute. Muri gahunda ya robo, insinga zifite umushinga wimiganya irashobora kwihanganira amamiriyoni yo kunama inzinguzingo cyangwa imbaraga zikomeye za torsianal idafite ibibazo. Igishushanyo nacyo kirimo kurwanya peteroli, ibisasu hamwe nimirasire ya ultraviolet. Byongeye kandi, bitewe nibikoresho, ni ubusa-ubusa na flame redibant, nikintu gifatika cyinsinga zibyemewe kandi zikoreshwa muri Amerika. Insinga zumuruko zikoreshwa mu mashini no kubaka uruganda, Automation Automation, hamwe n'inganda zimodoka.

PVC - Ikintu cyingenzi

Polyvinyl chloride (PVC) ni plastike yakoreshejwe mugukora ibicuruzwa bitandukanye kuva 1920. Nibicuruzwa byumurongo wa gaze polymeirionation ya vinyl chloride. Bitandukanye na Elastomer Pur, PVC ni polymockelestique. Niba ibikoresho byahindutse bihanganye, ntibishobora gusubizwa muburyo bwambere.

Nkibintu bifatika, chlolvinyl chloride itanga amahirwe atandukanye kuko ashoboye guhuza nibikenewe bitandukanye muguhindura ibipimo byayo. Ubushobozi bwaho bwo kwikorera mashini ntabwo ari hejuru nka phumu, ariko PVC nayo irashimishije mubukungu; Impuzandengo ya Polyurethane ni inshuro enye hejuru. Byongeye kandi, PVC ifite impumuro nke kandi irwanya amazi, acide n'abakozi basukura. Niyo mpamvu ikoreshwa kenshi munganda zibiribwa cyangwa mubidukikije. Icyakora, PVC ntabwo ari kure-yubuntu, niyo mpamvu ifatwa nkaho idakwiriye kubisabwa byimbere. Mubyongeyeho, ntabwo ari umuhangareka wa peteroli, ariko uyu mutungo urashobora kugerwaho ninyongeramuco idasanzwe.

Umwanzuro

Byombi Polyine na Polyvinyl chloride bifite ibyiza nibibi nkimigozi hamwe nibikoresho byo guhinduranya. Nta gisubizo gifatika kubintu byiza kuri buri porogaramu yihariye; Ahanini biterwa nibikenewe byihariye. Rimwe na rimwe, ibikoresho bitandukanye rwose birashobora kuba igisubizo cyiza. Kubwibyo, turashishikariza abakoresha gushaka inama zibihanga bamenyereye imitungo myiza kandi mibi yibikoresho bitandukanye kandi birashobora gupima.
