I-PET strap (i-polyester strap) inesikhathi sokugcina esinconywayo sezinyanga ezingu-18-36 ngaphansi kwezimo ezifanele. Izinga lokushisa, umswakama, ukuchayeka kwe-UV, nobuqotho bokupakisha konke kuthinta ukuthi ibhande le-PET ligcina ukusebenza kwalo isikhathi eside kangakanani.

Ukupakishwa komkhakha osindayo kudinga ibhande elibamba ngaphansi kwengcindezi eqhubekayo, limelana nokuhuzuka, futhi likwazi ukulondoloza isitoreji sangaphandle nokuhamba olwandle. Ibhande le-PET (ibhande le-polyester) nentambo ye-polyester zombili zisetshenziselwa ukuvikela umthwalo, kodwa zisebenza ngendlela ehluke kakhulu. Intambo ye-polyester iyelula ngaphansi komthwalo, ilahlekelwa ukushuba lapho impahla izinza, futhi ihubeka ngokushesha emaphethelweni ensimbi acijile.

Ibhande le-PET (ibhande le-polyester) litholakala ngobukhulu obusukela ku-0.4mm kuya ku-1.25mm, ububanzi ngalunye bufanele izidingo ezithile zomthwalo kanye nezinhlobo zemishini. Amabhande azacile (0.4–0.55mm) anikezela ngemithwalo emincane yephalethi nokupakishwa okuvamile, kuyilapho izinketho eziwugqinsi (0.8–1.25mm) zibamba amakhoyili ensimbi, amabhala kakotini, kanye nezinhlelo zokusebenza ezidingeka kakhulu zezimboni.

Ubukhulu obuyisisekelo buphakathi kokucaciswa okunganakwa kakhulu lapho abathengi bekhetha ibhande le-PET (ibhande le-polyester) ukuze basebenze ngokuzenzakalelayo. Ibhande elihlangabezana nazo zonke izidingo zomshini—ububanzi obulungile, ukujiya, namandla okuphuka—lisazobangela izinkinga zokuphakela uma usayizi walo oyinhloko ungafani nesikhiphi sekhanda esibophayo. Idayamitha emaphakathi engaphakathi, ububanzi beroli, kanye nobubanzi be-roll yangaphandle kufanele konke kuhambisane ne-spindle yomshini kanye nendlela yokuqaqa. Lo mhlahlandlela uchaza ubukhulu be-PET strap core, ukuthi buthinta kanjani ukusebenza kwekhanda lokubopha okuzenzakalelayo, kanye nendlela yokuqinisekisa ukuhambisana ngaphambi kokuthenga.

Ukukhetha phakathi kwebhande le-PET (ibhande le-polyester) kanye nebhande lensimbi kungenye yezinqumo ezibaluleke kakhulu ekufakweni kwezimboni. Ibhande le-PET linikeza ukonga izindleko ezingafika ku-50% ngonyawo ngalunye, liqeda izingozi zokulimala emiphethweni ebukhali kanye ne-snap-back, futhi linikeza ukugcinwa kwengcindezi ephakeme njengoba imithwalo ithula ngesikhathi sokuthutha. Izintambo zensimbi ziletha ukuqina okukhulu kwemithwalo enzima kakhulu kodwa ithwala izindleko ezifihliwe ezihlanganisa nezidingo eziphezulu zabasebenzi, ubungozi bokugqwala, nokuguga kwemishini. Ngokusho kwedatha yemboni, ibhande le-PET lihlinzeka ngokuphindwe kane komugqa ngethani ngalinye uma liqhathaniswa nensimbi, lishintsha ngokuyisisekelo isibalo sezindleko.

I-PET strap (i-polyester strap) itholakala ngobubanzi obujwayelekile obusuka ku-9mm kuya ku-32mm, enobukhulu obuvamile obuhlanganisa i-12mm, 16mm, 19mm, 25mm, ne-32mm. Ukukhetha ububanzi kuthinta ngokuqondile amandla ekhefu, ukusatshalaliswa komthwalo, nokuhambisana kwemishini. Ibhande le-PET elingu-19mm livamise ukuletha amandla okuphuka angu-450–550kg, kanti ibhande elingu-25mm lingadlula u-900kg—ukusondela ekusebenzeni kwebhande lensimbi ngesisindo esiphansi kakhulu nezindleko.

Ibhande le-PET (ibhande le-polyester) kanye ne-PP strap (ibhande le-polypropylene) yizinto ezimbili ezivame kakhulu zokubopha ipulasitiki, nokho zisebenzisa izinhloso ezihluke kakhulu. Nakuba ibhande le-PP linikeza ukuguquguquka nokusebenza kahle kwezindleko zokupakishwa komsebenzi okhanyayo, ibhande le-PET liletha amandla afana nensimbi ane-elongation ephansi, okuyenza ilungele imithwalo esindayo, isitoreji sangaphandle, nokuthunyelwa kwebanga elide. Lo mhlahlandlela uchaza ukuthi iyini i-PET strap, ukuthi ihluke kanjani ku-PP strap ezintweni ezibonakalayo nokusebenza, nokuthi ungayikhetha kanjani inketho efanele yohlelo lwakho lokusebenza oluthile.

I-PET strap (i-polyester strap) izindinganiso zokulawula ikhwalithi ziqinisekisa ukusebenza okungaguquki nokuphepha komthwalo. Ngokusho kokucaciswa kwe-ASTM D3950, ukuhlolwa kwekhwalithi kufanele kuqinisekise amandla aqinile, ubude, ukunemba kobukhulu, namandla ophawu lokushisa. Lo mhlahlandlela uchaza izindinganiso ezibalulekile zokulawula ikhwalithi, izimiso zokuhlola, nokuthi yini abathengi okufanele bayibheke lapho beqinisekisa ikhwalithi yebhande le-PET.

Amandla aqinile webhande le-PET ngokuvamile asukela ku-160 kuya ku-635 kilograms, kuye ngobukhulu bayo nekhwalithi yokukhiqiza. Lesi silinganiso simelela amandla amakhulu ibhande le-polyethylene terephthalate elingamelana nalo ngaphambi kokuba linqamuke, okukwenza kube yisici esibalulekile ekuthengweni kwempahla.

Ibhande le-PET (ibhande le-polyester) seliphenduke into ethandwayo yokubopha ezisetshenziswa embonini esindayo, esikhundleni sensimbi ekuhlanganisweni kwekhoyili yensimbi, ukuhlanganisa izitini, ukupakishwa kwebale kakotini, kanye nokuvikela izingodo. Ngamandla aqinile afika ku-600 N/mm², ukugcinwa kwengcindezi okuhle kakhulu, nokusebenza okungagqwali, ibhande le-PET liletha amandla afana nensimbi ngaphandle kokushiyeka kwensimbi. Ngokusho kokuhlaziywa kwemboni, ibhande le-PET lingakwazi ukufaka esikhundleni sensimbi emisebenzini eminingi enzima, yehlise izindleko eziphelele ngo-30-50% kuyilapho ithuthukisa ukuphepha kwabasebenzi futhi iqeda ukugqwala.
