PUR CYANGWA PVC: Hitamo Ibikoresho bikwiye

Mugihe ushakisha insinga nziza ninsinga, guhitamo ibikoresho byiza byo gukata ni ngombwa. Urupapuro rwo hanze rufite imirimo itandukanye kugirango irambe, umutekano n'imikorere ya kabili cyangwa insinga. Ntibisanzwe ko ugomba guhitamo hagati ya polyurethane (PUR) napolyvinyl chloride (PVC). Muri iyi ngingo, uziga kubyerekeye itandukaniro ryimikorere hagati yibikoresho byombi hamwe nibisabwa buri kintu kibereye.

Imiterere yimyenda nibikorwa mumigozi ninsinga

Urupapuro (nanone rwitwa sheath yo hanze cyangwa sheath) nigice cyo hejuru cyumugozi cyangwa insinga kandi gikoreshwa hakoreshejwe bumwe muburyo butandukanye bwo gusohora. Urupapuro rurinda imiyoboro ya kabili nibindi bikoresho byubatswe kubintu bituruka hanze nkubushyuhe, ubukonje, ubushuhe cyangwa imiti nubukanishi. Irashobora kandi gukosora imiterere nuburyo bwumuyoboro uhagaze, kimwe nigice cyo gukingira (niba gihari), bityo bikagabanya kwivanga kwa kabili ya electromagnetic ihuza (EMC). Ibi nibyingenzi kugirango habeho guhererekanya imbaraga, ibimenyetso, cyangwa amakuru muri kabili cyangwa insinga. Sheathing nayo igira uruhare runini mugihe kirekire cyinsinga ninsinga.

Guhitamo ibikoresho byiza byo gukata nibyingenzi kugirango umenye umugozi mwiza kuri buri porogaramu. Kubwibyo, ni ngombwa kumenya neza intego umugozi cyangwa insinga bigomba gukorera hamwe nibisabwa bigomba kuba byujuje.

Ibikoresho bisanzwe byo gukata

Polyurethane (PUR) na polyvinyl chloride (PVC) nibikoresho bibiri bikoreshwa cyane mu gukata insinga ninsinga. Mubigaragara, nta tandukaniro riri hagati yibi bikoresho, ariko byerekana imitungo itandukanye ituma bikwiranye na porogaramu zitandukanye. Byongeye kandi, ibindi bikoresho byinshi birashobora gukoreshwa nkibikoresho byo gukata, birimo reberi yubucuruzi, elastomeri ya termoplastique (TPE), hamwe nibikoresho bya pulasitiki byihariye. Ariko, kubera ko bitagaragara cyane ugereranije na PUR na PVC, tuzagereranya gusa ibi bibiri mugihe kizaza.

PUR - Ikintu cyingenzi

Polyurethane (cyangwa PUR) bivuga itsinda rya plastiki ryakozwe mu mpera za 1930. Ikorwa nuburyo bwimiti yitwa polymerisation. Ibikoresho fatizo mubisanzwe ni peteroli, ariko ibikoresho byibimera nkibirayi, ibigori cyangwa beterave yisukari nabyo birashobora gukoreshwa mubikorwa byayo. Polyurethane ni elastomer ya thermoplastique. Ibi bivuze ko byoroshye iyo bishyushye, ariko birashobora gusubira muburyo bwambere iyo bishyushye.

Polyurethane ifite imiterere myiza yubukanishi. Ibikoresho bifite imbaraga zo kwihanganira kwambara, kugabanya kurwanya no kurira, kandi bikomeza guhinduka cyane no mubushyuhe buke. Ibi bituma PUR ikwiranye cyane na porogaramu zisaba kugenda ningendo zisabwa, nkurunigi rukurura. Mubikorwa bya robo, insinga zifite PUR zirashobora kwihanganira amamiriyoni yunama cyangwa imbaraga zikomeye za torsional nta kibazo. PUR ifite kandi imbaraga zikomeye zo kurwanya amavuta, imishwarara hamwe nimirasire ya ultraviolet. Byongeye kandi, ukurikije ibigize ibikoresho, ni halogen-idafite na flame retardant, ibyo bikaba ari ingingo ngenderwaho zingenzi ku nsinga zemewe na UL kandi zikoreshwa muri Amerika. Intsinga za PUR zikoreshwa cyane mubwubatsi bwimashini ninganda, gukoresha inganda, ninganda zitwara imodoka.

PVC - ikintu cyingenzi

Polyvinyl chloride (PVC) ni plastiki yakoreshejwe mu gukora ibicuruzwa bitandukanye kuva 1920. Nibicuruzwa bya gazi ya polymerisation ya vinyl chloride. Bitandukanye na elastomer PUR, PVC ni polymer ya termoplastique. Niba ibikoresho byahinduwe munsi yubushyuhe, ntibishobora gusubizwa uko byahoze.

Nkibikoresho byo gukata, polyvinyl chloride itanga uburyo butandukanye kuko ishoboye guhuza nibikenewe bitandukanye ihindura igipimo cyayo. Ubushobozi bwimikorere yubukanishi ntabwo buri hejuru nka PUR, ariko PVC nayo ifite ubukungu cyane; Impuzandengo ya polyurethane yikubye inshuro enye. Byongeye kandi, PVC nta mpumuro nziza kandi irwanya amazi, aside hamwe nisuku. Niyo mpamvu akenshi ikoreshwa mu nganda zibiribwa cyangwa ahantu h’ubushuhe. Ariko, PVC ntabwo halogen-yubusa, niyo mpamvu ifatwa nkaho idakwiriye kubisabwa murugo. Byongeye kandi, ntabwo isanzwe irwanya amavuta, ariko uyu mutungo urashobora kugerwaho ninyongeramusaruro yihariye.

Umwanzuro

Polyurethane na polyvinyl chloride byombi bifite ibyiza nibibi nkibikoresho byo gukata insinga. Nta gisubizo gifatika cyibikoresho byiza kuri buri porogaramu yihariye; Byinshi biterwa nibyifuzo bya buri muntu ku giti cye. Rimwe na rimwe, ibikoresho bitandukanye rwose birashobora kuba igisubizo cyiza. Kubwibyo, turashishikariza abakoresha gushaka inama kubuhanga bamenyereye ibyiza nibibi byibikoresho bitandukanye kandi bishobora gupima.
