1. Izici ze-TPEibhande lokumelana
Izinto ze-TPE zinokuqina okuhle namandla aqinile, futhi izwakala inethezekile futhi ibushelelezi.Ikhishwa ngokuqondile futhi yenziwe yi-extruder, futhi ukucutshungulwa kulula futhi kulula.I-TPE inokumelana nowoyela okungekuhle.I-TPE ivutha ngephunga elimnandi, futhi intuthu incane futhi ilula.
Impahla ye-TPE iyimpahla ehlanganisiwe ehlanganisiwe, futhi izakhiwo zayo ezibonakalayo zinokulungiseka okuningi, futhi amandla adonsela phansi athile aphakathi kuka-0.89 no-1.3.Ubulukhuni buvamise ukuba phakathi kuka-28A-35A Shore.Ukuqina okuphezulu kakhulu noma okuphansi kakhulu kuzothinta ukusebenza kwe-ibhande lokumelana.
Idatha ye-TPEibhande lokumelana impahla isebenzisa i-SEBS njengento eyinhloko.I-SEBS iphinde ibe into evumelana nemvelo ehlangabezana nezinga le-REACH, ngakho-ke ngeke ibangele ukungezwani namaqembu akhethekile.Ibhande elinwebekayo elenziwe nge-TPE linobuso obushelelezi, alinazo izinhlayiya nezinto zangaphandle, futhi lisagcina ukunwebeka okuhle kakhulu endaweni yokushisa ephansi ngaphandle kokuba lukhuni futhi brittle.Ukumelana nesimo sezulu esihle kakhulu, kungasetshenziswa endaweni engama-40-90 degrees Celsius, futhi ngeke kube nokuqhekeka ekusetshenzisweni kwangaphandle ngaphakathi kwalolu banga lokushisa.
Izinto eziyinhloko ezisetshenziswa ku-TPE, i-SEBS, iqukethe inani elikhulu le-butadiene, elinezici zesilinganiso esiphezulu sokwelula kanye nokuguqulwa okuncane.Sihlole ukuthi ukwelula izikhathi ezi-3 izikhathi ezingaphezu kuka-30,000 kuzodala ukuwohloka okuncane, kodwa kungabi ngaphezu kuka-5%.
2. Izici ze-latexibhande lokumelana
I-Latex inokumelana okuhle nokugqokwa, ukumelana nokushisa, ukunwebeka okuphezulu kakhulu, amandla okudabula kanye nobude izikhathi ezingaphezu kweziyi-7.Kulula ukuguga emoyeni, kube mhlophe uma ufutha isithwathwa.Ngenxa yokuba khona kwama-molecule e-heterogeneous protein ku-latex yemvelo, kungase kubangele ukungezwani komzimba kubantu abathile.
I-latex yemvelo isikwa esihlahleni senjoloba.Iwuhlobo lwenjoloba yemvelo.Iwuketshezi, imhlophe njengobisi, futhi ayinambitheki.I-latex yemvelo entsha iqukethe u-27% kuya ku-41.3% werabha, u-44% kuya ku-70% wamanzi, u-0.2% kuya ku-4.5% wamaprotheni, u-2% kuya ku-5% we-resin yemvelo, u-0.36% ukuya ku-4.2% ushukela, no-0.4% umlotha.Ukuze uvimbele i-latex yemvelo ukuthi ingahlangani ngenxa yama-microorganisms ayo kanye nama-enzyme, i-ammonia nezinye iziqinisi zamakhemikhali zivame ukungezwa.
Risistance band I-latex ingcono noma i-tpe ingcono, kokubili kunezinzuzo kanye nokubi.Isetshenziswa emkhakheni weibhande lokumelanas, ukukhetha kwezinto ze-TPE kukwazi ngokugcwele ukusebenza kwayo, futhi intengo ishibhile.Uma uqhathanisa lezi zinto ezimbili, akukho okuhle noma okubi.Kusafanele sinqume ngokuvumelana nokusebenza kanye nezidingo zokusetshenziswa komkhiqizo.
2. Umehluko phakathi kwe-TPUibhande lokumelana kanye ne-TPEibhande lokumelana
Nakuba i-TPU ne-TPE ingumehluko wezinhlamvu, ukusetshenziswa kwe-TPUibhande lokumelana kanye ne-TPEibhande lokumelana yehluke kakhulu.Inani elincane le-TPUibhande lokumelana ikhanya emkhakheni wezesekeli zezingubo eziboshwe, njengekhola kanye nezigqoko zezingubo eziboshwe, i-shoulder seam kanye nezinhlangothi ezihlangothini.Okuthatha ukunwebeka kwe-TPE ukuthi umzila wamandla unesimo esithile kumishini yokufaneleka, njengokufanelekaibhande lokumelanas, amabhendi wokuqina wemishini yokuqina nokunye.Noma ngabe i-TPUibhande lokumelana noma i-TPEibhande lokumelana, azivumelani nemvelo futhi zihlala isikhathi eside.Umehluko obaluleke kakhulu phakathi kwazo umehluko wobubanzi bokubukeka nobukhulu kanye nobubanzi bokusetshenziswa.Yiqiniso, izinto zokusetshenziswa nazo zihluke kancane.
1. Umehluko ekubukekeni kanye nobubanzi bokusetshenziswa
Umbala we-TPUibhande lokumelana ikakhulukazi i-frosted esobala, ngokuvamile ububanzi buphakathi kuka-2MM no-30MM, futhi ukujiya kuphakathi kuka-0.08MM no-1MM.Isetshenziselwa ikhola kanye nezintambo zezingubo eziboshwe, futhi i-shoulder seam side seams ibunjwa ukuze inikeze umphumela omuhle ongabonakali.Asikho isidingo sokucabangela ukufanisa umbala;ububanzi bawo ngokuvamile bufana nobubanzi be-stitches, okwenza kube lula ukufihla ibhande;ubukhulu obuncane obuncane ngeke buthinte ukunethezeka kwezingubo eziboshwe ngemuva kokuthunga.
Umbala we-TPEibhande lokumelana ihlukene kakhulu, njengombala wemvelo, oluhlaza okwesibhakabhaka, ophuzi, oluhlaza okotshani, obomvu, owolintshi, opinki, onsomi, njll. Ububanzi obujwayelekile bungu-75-150mm, kanti ukujiya buyi-0.35mm, 0.45mm, 0.55mm, 0.65mm, njll. ., Imibala iyahlukahluka futhi ilungele abasebenzisi ukuthi bayikhethe.Ngoba i-TPEibhande lokumelana ibanzi futhi ishubile, ingamelana nokushuba kangcono futhi ifanele ukusetshenziswa emishinini yokuqina.
2. Umehluko phakathi kwezinto ezingavuthiwe
Kokubili i-TPU ne-TPE yizinto ze-thermoplastic ezinokunwebeka kwerabha, futhi zombili zinokunwebeka okuhle kwerabha.Uma kuqhathaniswa, i-TPE inhle kakhulu ngokuya ngenduduzo ethintekayo, futhi i-TPU inokunwebeka okuhle kakhulu namandla.Kunzima ukuhlukanisa phakathi kwe-TPE ne-TPU ngokubheka okubonakalayo kuphela.Qala ngemininingwane ukuze uhlaziye umehluko nomehluko phakathi kwe-TPE ne-TPU:
1) Ukucaca kwe-TPU kungcono kune-TPE, futhi akulula ukunamathela njenge-TPE esobala;
2) Ubukhulu obuthile be-TPU buhluka kakhulu, kusukela ku-1.0 kuya ku-1.4, kuyilapho i-TPE iphakathi kuka-0.89 kuya ku-1.3, ikakhulukazi ngendlela yezingxube, ngakho amandla adonsela phansi athile ashintsha kakhulu;
I-3) I-TPU inokumelana nowoyela okungcono, kuyilapho i-TPE inokumelana nowoyela okungekuhle;
I-4) I-TPU ivutha ngephunga elilula, ngentuthu encane futhi elula, futhi kukhona umsindo omncane wokuqhuma lapho uvutha, i-TPE inephunga elilula lapho ivutha, futhi intuthu incane futhi ilula;
5) Ukunwebeka kwe-TPU nokusebenza kokululama okunwebekayo kungcono kune-TPE;
6) Ukumelana nezinga lokushisa kwe-TPU kungu--60 degrees Celsius kuya ku-80 degrees Celsius, i-TPE ingu -60 degrees Celsius kuya ku-105 degrees Celsius;
I-7) Mayelana nokubukeka nomuzwa, kweminye imikhiqizo ehlanganiswe ngokweqile, imikhiqizo ye-TPU inomuzwa oqinile kanye nokumelana okuqinile okungqubuzanayo kunemikhiqizo ye-TPE;kuyilapho imikhiqizo ye-TPE inomuzwa othambile futhi othambile nokusebenza kokungqubuzana okubuthakathaka.
Ngokuvamile, i-TPUibhande lokumelana isobala futhi ineqhwa, ilula futhi ithambile, inokuqina okuhle, ukuqina okuhle, futhi akulula ukuphuka.Ifanele i-knitwear collar cuff hemming kanye ne-shoulder seam side seam setting.Idatha ye-TPEibhande lokumelana inemibala ehlukahlukene, ikhululekile uma uyithinta, inezinga eliphezulu lokunwebeka, futhi inokuqina okuhle kakhulu.Ilungele ukusetshenziswa kumishini yokuqina.
