Gutegura no kubiranga polyurethane igice cya pomo-rigid foam kumaboko yibikorwa byimikorere.
Intoki mu gihugu imbere ni igice cyingenzi cya cab, kigira uruhare rwo gusunika no gukurura umuryango no gushyira ukuboko k'umuntu mu modoka. Mugihe byihutirwa, mugihe imodoka hamwe no kugongana kwamaboko byoroshye kandi byahinduwe pp (polpropylene), abs (polfrylonike) nibindi bikaba, bityo bikagabanya gukomeretsa. Polyurethane yoroheje yoroheje irashobora gutanga ikiganza cyiza kumva kandi uburyo bwiza bwo hejuru, bityo bitera ihumure nubwiza bwa cockpit. Kubwibyo, hamwe niterambere ryinganda zimodoka no kunoza ibyo abantu basabwa kubikoresho byimbere, ibyiza bya Polyurethane yoroheje mumaboko yimodoka bigenda cyane.
Hariho ubwoko butatu bwa polyurethane yoroshye: kwihangana kwifuzwa cyane, kwifungisha kwifuzwa na sem. Ubuso bwo hanze bwimbaraga zubucuruzi bwimbitse butwikiriwe na PVC (polyvinyl chloride) uruhu, kandi imbere ni Polyurethane imbaraga ndende. Inkunga ya furo ifite intege nke, imbaraga ni hasi cyane, kandi amazina hagati yifuro nuruhu ntibihagije. Ukuboko kwikinisha kwikinisha bifite igice cyifuro cyuruhu, ikiguzi gito, urwego rwo kwishyira hamwe, kandi rukoreshwa cyane mubinyabiziga byubucuruzi, ariko biragoye kuzirikana imbaraga zubuso hamwe nibihumuriza muri rusange. Intoki za Semi-Rigid zitwikiriwe n'uruhu rwa PVC, uruhu rutanga gukoraho neza no kugaragara, hamwe no gutandukana kw'imbere, kwinjiza neza, bityo birakoreshwa cyane mu gukoresha Imbere y'abagenzi.
Muri iyi mpapuro, formula yibanze ya polyurethane igice cya Polurethane igice cyateguwe kubikorwa byimodoka byateguwe, kandi iterambere ryayo ryize kuri iyi.

Gutegura formula yibanze na sample
Gushiraho ishingiro rya Selyurethane ya Polyurethane bwerekanwe mu mbonerahamwe ya 1.
Imyiteguro yimiterere yikizamini cyicyitegererezo: Polyporite (ibikoresho) byateguwe ukurikije imiterere yihuta, hanyuma usuka hamwe na folport yihuta, hanyuma igasuka hamwe nigikoresho cyihuta cyahinduwe, hanyuma gisuka hamwe nigikoresho cyihuta cyanditseho. icyitegererezo.
Gutegura icyitegererezo cyo kwipimisha imikorere: Igice cyuruhu rwa PVC gishyizwe muri kaburimbo yo hasi, hamwe na PILYent MDI ivanze muburyo bwo kwihuta, hanyuma igasunikwa nigikoresho cyihuta cyane, hanyuma igasunikwa nigikoresho cyihuta cyane, hamwe nuruhu rwa polyine hamwe nuruhu rwabumbwe mugihe runaka.
Ikizamini cyimikorere
Imashini ya mashini: 40% CLD (Harresne ya Gukora) ukurikije iso-3386 ikizamini gisanzwe; Imbaraga za tensile no kwihitiramo kurenga kugeragezwa ukurikije ISO-1798; Imbaraga za Tear zigeragezwa ukurikije iso-8067. Imikorere ihuza: Imashini ya elegitoroniki yakoreshejwe mugushinyagurika kuruhu no kubara 180 ° ukurikije ibipimo byayo.
Imikorere yimibare: Gerageza Kubura imitungo nubutaka nyuma yamasaha 24 yo gusaza saa 120 ℃ ukurikije ubushyuhe busanzwe bwa OEM.
Ibisubizo n'ibiganiro
Umutungo wa mashini
Muguhindura igipimo cya Polyyer polyol a na polymer polyOl b muburyo bwibanze, ingaruka za polyether zitandukanye kumutungo wa esikatifiya ya selyurethane ya eccurethane ya poluythane, nkuko bigaragara mu mbonerahamwe ya 2.
Irashobora kugaragara mubisubizo biri mu mbonerahamwe ya 2 ko igipimo cya Polyyer polydol a to polymer polymer polyol b gifite ingaruka zikomeye kumiterere ya polyurethane ya Polourethane. Igihe igipimo cya Polyyer Polyol A kugeza Polymer Polymer B yiyongera, kwihitiramo ikiruhuko bigabanuka ku rugero runaka, kandi imbaraga za tensile no gutanyagura imbaraga zo guhindura bike. Urunigi rwa molekile rwa Polyurethane cyane rugizwe nigice cyoroshye hamwe nigice cyoroshye, igice cyoroshye kuva polimal nibice bikomeye bivuye kuri carbamate. Ku ruhande rumwe, uburemere bwa molekile ugereranije na hydroxyl byagaciro byombi biratandukanye, kurundi ruhande, Polymer PolyOl B ni PolyOl PILYONILE na Styree, kandi gukomera, byongera ibintu bito bya molekitri, bikaba byongera imbogamizi y'ifuro. Igihe Polyether polyol A ni ibice 80 na polymer polyOl b ni ibice 10, imiterere yuzuye yubuka ifuro nibyiza.
Umutungo
Nkibicuruzwa bifite inkunga yo hejuru, hazagabanya cyane uburyo bwibice niba ifuro nimpu, imikorere yihungabana ya polyurethane nuruhu. Hashingiwe ku bushakashatsi bwavuzwe haruguru, abatatanye butandukanye bongerewe kugerageza imitungo y'ibifum n'uruhu. Ibisubizo byerekanwe mu mbonerahamwe ya 3.
Irashobora kugaragara ku mbonerahamwe ya 3 kugirango ipasaburindi zitose zifite ingaruka zigaragara ku mbaraga zishingiye ku ifuro n'uruhu: bishobora guterwa no gufungura cyane ifuro nyuma yo kongeramo 2; Nyuma yo gukoresha inyongeramvuri 1 na 3, imbaraga zizerera ingano zubusa zifite ubwiyongere bwa 1 ni hejuru ya 17% kurenza urugero rwa metero 25%. Itandukaniro riri hagati yinyongera 1 kandi wongeyeho 3 riterwa ahanini nitandukaniro mububiko bwibikoresho bigizwe hejuru. Muri rusange, gusuzuma urubuga rwamazi ku buhamye, inguni yo guhuza nikintu cyingenzi kugirango upime ubuso bwubutaka. Kubwibyo, inguni itunganijwe hagati yibikoresho byubahirizwa nuruhu nyuma yo kongeramo ibirenze ibitatanye bibiri byageragejwe, kandi ibisubizo byerekanwe ku gishushanyo cya 1.
Birashobora kugaragara kuva 1 kugirango inguni yimiterere yicyitegererezo cyubusa nicyo kinini, kiba ari 27 °, kandi inguni yumubano wumukozi wafasha 3 ni muto, ari 12 ° ari hafi 12 °. Ibi birerekana ko gukoresha ibiyobyabwenge 3 birashobora guteza imbere uruhara rwibikoresho bigizwe nurugero runini, kandi biroroshye gukwirakwira hejuru yuruhu, kandi biroroshye gukwirakwira hejuru yuruhu, bityo biroroshye gukwirakwira hejuru yuruhu, bityo bikaba byoroshye gukoresha 3 bifite imbaraga zikomeye zo gukuramo.
Umutungo ushaje
Ibicuruzwa byakangurirwa mu modoka, inshuro z'umutara ku zuba ni ndende, kandi imikorere y'ikirenga ni ikindi gikorwa cy'ingenzi Polyinethane Semi-Rigid Handrail Foam agomba gusuzuma. Kubwibyo, imikorere yo gusaza formula yibanze yageragejwe kandi ubushakashatsi bunoze bwakorwaga, kandi ibisubizo byerekanwe mu mbonerahamwe ya 4.
Mugereranije amakuru mu mbonerahamwe ya 4, urashobora kubona ko imitungo ya mashini igabanuka cyane nyuma yo gusaza 12h, nyuma yo gusaza indi mitungo itandukanye usibye 13% ~ 16%; Gutakaza imikorere ya 24h ass 23% ~ 26%. Byerekanwa ko imitungo yo gusaza yubushyuhe ntabwo ari nziza, kandi imitungo yo gusaza yubushyuhe bwa formulaire yumwimerere irashobora kunozwa no kongeramo icyiciro cya antioxident a kuri formulaila. Mubihe bimwe byageragejwe nyuma yo kongeramo antioxident a, gutakaza imitungo itandukanye nyuma ya saa moya zari 7h00 ~ 8%, kandi gutakaza imitungo itandukanye nyuma ya 24h 16% ~ 16%. Kugabanuka kwamashanyarazi ahanini biterwa nuruhererekane rwibitabo byaciwe nububiko bwimiti no gukora imiti yubusa mugihe cyubushyuhe, buturuka ku mpinduka shingiro mu miterere cyangwa imiterere yibintu byumwimerere. Ku ruhande rumwe, kugabanuka mu mikorere yo guhuza bitewe no kugabanuka mu buryo bwa mashini mu miterere y'ibibyimba ubwayo, na plastisar yimuka hejuru mu gihe cyo gusaza Thermal. Hiyongereyeho antioxidants irashobora kunoza imiterere yubushyuhe, cyane cyane Antioxydants irashobora gukuraho imirasire yubusa, gutinda cyangwa kubuza inzira ya okiside ya polymer, kugirango ukomeze imitungo yumwimerere ya polymer.
Imikorere Yuzuye
Ukurikije ibisubizo byavuzwe haruguru, formula nziza yateguwe kandi imitungo yayo itandukanye yasuzumwe. Imikorere ya formula yagereranijwe n'iya Jelyurethane muri Polyurethane ndende yongeye gusubirwamo. Ibisubizo byerekanwe mu mbonerahamwe ya 5.
Nkuko bigaragara ku mbonerahamwe ya 5, imikorere ya polyure nziza ya powemu ifite ibyiza bifite inyungu zimwe na zimwe kuri formulaire na rusange, kandi ni ngirakamaro cyane, kandi birakwiriye gukurikiza imirimo yimbere.
Umwanzuro
Guhindura ingano ya polyEther hanyuma uhitemo intungamubiri zujuje ibyangombwa na Antioxidant irashobora guha igice cya polyurethane cya polyurethane cyiza cyiza cya mashini Dushingiye ku mikorere myiza y'ifuro, iyi relyurethane yo mu rwego rwo hejuru ya powemu ya polyurethane irashobora gukoreshwa kubikoresho bya buffer ya buffer nkintoki n'ibikoresho.
