Abakiriya benshi batangaje ko TPU ikorera mu mucyo iyo ikozwe bwa mbere, kuki ihinduka neza nyuma yumunsi kandi igasa ibara ryumuceri nyuma yiminsi mike? Mubyukuri, TPU ifite inenge karemano, ni uko igenda ihinduka umuhondo mugihe runaka. TPU ikuramo ubuhehere buturuka mu kirere igahinduka umweru, cyangwa ibi biterwa no kwimuka kw'inyongeramusaruro zongewe mugihe cyo gutunganya. Impamvu nyamukuru nuko amavuta atagaragara, naho umuhondo ni ikiranga TPU.
TPU ni ibara ry'umuhondo, kandi MDI muri ISO izahinduka umuhondo munsi ya UV irrasiyoya, byerekana ko umuhondo wa TPU ari umutungo. Kubwibyo, dukeneye gutinza igihe cyumuhondo wa TPU. Nigute ushobora kubuza TPU umuhondo?
Uburyo bwa 1: Irinde
1. Hitamo guteza imbere ibicuruzwa byirabura, umuhondo, cyangwa umwijima mubyiciro byambere byo guteza imbere ibicuruzwa bishya. Nubwo ibyo bicuruzwa bya TPU bihinduka umuhondo, isura yabyo ntishobora kuboneka, mubisanzwe ntakibazo gihari.
2. Irinde imirasire y'izuba itaziguye kuri PU. Ahantu ho kubika PU hagomba kuba hakonje kandi hahumeka, kandi PU irashobora gupfunyika mumifuka ya pulasitike igashyirwa ahantu hatagaragara izuba.
3. Irinde kwanduza mugihe cyo gukora intoki. Ibicuruzwa byinshi bya PU byanduye mugihe cyo gutondeka cyangwa gukiza, bikavamo umuhondo nko kubira ibyuya byabantu hamwe na solge organic. Kubwibyo, ibicuruzwa bya PU bigomba kwitondera byumwihariko isuku yumubiri uhuza kandi bigabanya uburyo bwo gutondeka bishoboka.
Uburyo bwa 2: Ongeramo ibirungo
1. Hitamo mu buryo butaziguye ibikoresho bya TPU byujuje ubuziranenge bwa UV.
2. Ongeramo imiti irwanya umuhondo. Kugirango uzamure ubushobozi bwo kurwanya umuhondo wibicuruzwa bya PU, akenshi birakenewe kongeramo imiti yihariye yo kurwanya umuhondo kubikoresho fatizo. Nyamara, imiti irwanya umuhondo ihenze, kandi tugomba no gutekereza ku nyungu zubukungu mugihe tuyikoresha. Kurugero, umubiri wumukara ntiwumva umuhondo, kuburyo dushobora gukoresha ibikoresho bihendutse bitarwanya umuhondo bidafite imiti igabanya ubukana. Nkuko imiti irwanya umuhondo ari ibikoresho byongeweho byongewe mubice A, dukenera kubyutsa mugihe bivanze kugirango tugabanye kimwe hamwe ningaruka zo kurwanya umuhondo, bitabaye ibyo umuhondo waho urashobora kubaho.
3. Shira irangi ry'umuhondo. Mubusanzwe hariho uburyo bubiri bwo gusiga amarangi, bumwe buri mugutera imiti naho ubundi ntibuterwa. Gutera irangi ryumuhondo birwanya ibara bizakora urwego rwo gukingira hejuru yibicuruzwa byarangiye PU, birinde umwanda n'umuhondo biterwa no guhura hagati yuruhu rwa PU nikirere. Iyi fomu irakoreshwa cyane.
Uburyo bwa 3: Gusimbuza ibikoresho
TPU nyinshi ni impumuro nziza ya TPU, irimo impeta ya benzene kandi irashobora gukurura byoroshye urumuri ultraviolet kandi igatera umuhondo. Ninimpamvu yibanze yo guhumeka ibicuruzwa bya TPU. Kubwibyo, abantu mu nganda bafata anti ultraviolet, kurwanya umuhondo, kurwanya gusaza na anti ultraviolet ya TPU nkigitekerezo kimwe. Inganda nyinshi za TPU zateje imbere alifatique TPU kugirango ikemure iki kibazo. Molekile ya Aliphatic TPU ntabwo irimo impeta ya benzene kandi ifite ifoto nziza, ntizigera ihinduka umuhondo
Birumvikana ko alifatique TPU nayo ifite ibibi byayo uyumunsi:
1. Urwego rukomeye ni ruto, muri rusange hagati ya 80A-95a
2. Inzira yo gutunganya iritondewe kandi yoroshye kuyitunganya
3. Kubura gukorera mu mucyo, birashobora gusa kugera kuri transparency ya 1-2mm. Ibicuruzwa byijimye bisa nibicu
