Ukukhetha phakathi kwamabakala okubopha iPP kuchaphazela ukusebenza kwexesha elide ngaphezu kokuba uninzi lwabathengi becinga. I-high-viscosity polypropylene strapping-eveliswa kwi-resin kunye ne-intrinsic viscosity phakathi kwe-0.60 kunye ne-0.95 dl / g-inika ubude be-molecular chain chain, okubangelwa amandla aphezulu, ukuxhathisa okungcono, kunye nokuphuculwa kokugcinwa kokusebenza kwexesha. Umtya we-PP womgangatho osemgangathweni unokusebenza ngokufanelekileyo kwizicelo zexeshana elifutshane okanye ezilula kodwa unokuphulukana noxinzelelo ngokukhawuleza phantsi komthwalo ozinzileyo. Eli nqaku lithelekisa amabakala omabini kulwakhiwo lwemolekyuli, iipropathi zoomatshini, kunye nokusebenza kwexesha elide ukunceda abathengi ukuba bakhethe ingcaciso echanekileyo.

Ukukhetha phakathi kwe-PET strap (i-polyester strap) kunye ne-steel strapping yenye yezona zigqibo zibalulekileyo kwi-industrial package. Umtya we-PET unikezela ukuya kuthi ga kwi-50% yokonga ngenyawo nganye, ususa imingcipheko yokulimala kwimida ebukhali kunye ne-snap-back, kwaye ibonelela ngokugcinwa koxinzelelo oluphezulu njengoko imithwalo ihlala ngexesha lokuhamba. Iintambo zentsimbi zihambisa ubungqongqo kwimithwalo egqithisileyo kodwa zithwala iindleko ezifihlakeleyo ezibandakanya iimfuno eziphezulu zabasebenzi, umngcipheko wongcoliseko lomhlwa, kunye nokunxitywa kwezixhobo. Ngokwedatha yeshishini, umtya we-PET ubonelela ngokuphindwe kane kumgca ocacileyo ngetoni nganye xa kuthelekiswa nentsimbi, itshintsha ngokusisiseko i-equation yeendleko.

I-PP strapping (i-polypropylene strapping) iyona nto isetyenziswa kakhulu kwimitya yokubopha ukukhanya ukuya kwi-medium-duty-duty-package applications. Yenziwe kwi-polypropylene resin ngokusebenzisa i-extrusion kunye neenkqubo zokwelula, i-PP strapping idibanisa ukuguquguquka, indleko-ukusebenza, kunye nokulula ukusetyenziswa. NgokukaSignode, umenzi ohamba phambili wokubopha imitya, iPP yokubopha yenzelwe i-palletizing, unitizing, bundling, ukuvalwa kwekhathoni kunye nokomeleza.

I-PET strap (i-polyester strap) ifumaneka kububanzi obuqhelekileyo ukusuka kwi-9mm ukuya kwi-32mm, kunye nobukhulu obuqhelekileyo obuquka i-12mm, 16mm, 19mm, 25mm, kunye ne-32mm. Ukukhetha Ububanzi buchaphazela ngokuthe ngqo amandla ekhefu, ukuhanjiswa komthwalo, kunye nokuhambelana kwezixhobo. Umtya we-PET we-19mm ngokuqhelekileyo uhambisa amandla okuphuka kwe-450-550kg, ngelixa i-strap ye-25mm ingadlula i-900kg-ukusondela ekusebenzeni kwentsimbi yentsimbi kwisisindo esiphantsi kakhulu kunye neendleko.

I-PP strap (i-polypropylene strap) ifumaneka kububanzi obuqhelekileyo ukusuka kwi-5mm ukuya kwi-19mm, kunye nobukhulu obuqhelekileyo obuquka i-5mm, 9mm, 12mm, 15mm, kunye ne-19mm. Ukukhetha ububanzi kuchaphazela ngokuthe ngqo ukuhanjiswa komthwalo, amandla okuphuka, kunye nokuhambelana kwezixhobo. Esi sikhokelo sichaza iinketho zobubanzi obuqhelekileyo obukhoyo, indlela yokukhetha ububanzi obufanelekileyo kwisicelo sakho, kunye nefuthe lokusebenza kobungakanani ngamnye. Imigangatho yoshishino ibonisa ukuba ububanzi bumisela ukusebenza komtya kwiinkalo ezintathu ezibalulekileyo: ukuhanjiswa komthwalo kuwo wonke umphezulu wepakethe, ukomelela kwekhefu kunye nomthamo womthwalo, kunye nokuhambelana kwe-chute yezixhobo.

I-PET strap (i-polyester strap) kunye ne-PP strap (i-polypropylene strap) zezona zinto zixhaphakileyo zokubopha iplastiki, kodwa zisebenza ngeenjongo ezahlukileyo. Ngelixa i-PP strap inikezela ukuguquguquka kunye nokusebenza kakuhle kweendleko zokupakishwa kokukhanya, i-PET strap ihambisa amandla afana nentsimbi kunye ne-elongation ephantsi, eyenza ilungele imithwalo enzima, ukugcinwa kwangaphandle, kunye nokuthunyelwa komgama omde. Esi sikhokelo sichaza ukuba yiyiphi i-PET strap, indlela eyahluke ngayo kwi-PP strap kwizinto eziphathekayo kunye nokusebenza, kunye nendlela yokukhetha ukhetho olufanelekileyo kwisicelo sakho esithile.

Umtya wePP (i-polypropylene strap) yeyona nto isetyenziswa kakhulu kwimitya yokubopha ukukhanya ukuya kophakathi kwezicelo zokupakisha kwihlabathi jikelele. Eli nqaku liphendula imibuzo emibini ebalulekileyo: yintoni kanye kanye i-PP strap, kwaye isetyenziselwa ntoni? Sichaza indlela i-PP strap eyenziwa ngayo-ukusuka kwi-polypropylene resin extrusion ukuya kwi-molecular orientation ehambisa amandla kunye nokuguquguquka-kwaye iphonononge izicelo zayo eziphambili kwi-palletizing, i-bundling, ukuvalwa kweekhathoni, kunye nokuzaliseka kwe-e-commerce. Ngokhetho lobubanzi ukusuka kwi-5mm ukuya kwi-19mm, ubukhulu ukusuka kwi-0.35mm ukuya kwi-0.8mm, kunye nemikhosi yokuqhawula ukusuka kwi-45kg ukuya kwi-230kg, umtya wePP ulungelelanisa kwiimfuno ezahlukeneyo zokupakisha ngelixa unikezela ngexabiso elisebenzayo.

Ukuqinisekisa i-PET strap (i-polyester strap) umgangatho ngaphambi kokwamkelwa kuthintela ukungaphumeleli komthwalo weendleko kunye nokuphazamiseka kokusebenza. Esi sikhokelo sibandakanya amanyathelo okuqinisekisa aphambili abandakanya uvavanyo lwamandla okuphumla, ukulinganisa ukuchaneka komgangatho, ukuhlolwa komphezulu kunye nophononongo lwamaxwebhu. Ngokweenkcazo ze-ASTM D3950, ukuqinisekiswa komgangatho kufuneka kuqinisekise amandla okuqina, ubude, kunye nokunyamezelwa komda. Ukulandela inkqubo yokuqinisekisa eyakhiweyo kunceda iingcali zokuthengwa kwempahla ziqinisekise ukuba umtya ofunyenweyo uhlangabezana neemfuno ezichaziweyo.

Iintambo zokupakisha ezizihambelayo zifuna ukubotshwa kwentambo ezondla ngokuthembekileyo, itywine ngokungaguqukiyo, kwaye igcine uxinezeleko ngesantya esiphezulu. I-PP strap (i-polypropylene strapping) iyona nto ikhethwayo kwizinto ezininzi ezizenzekelayo ze-carton kunye ne-pallet yokupakisha imisebenzi ngenxa yokuguquguquka kwayo, ukuguquguquka kwe-dimensional, kunye nokuhambelana noomatshini bokubopha ngokuzenzekelayo. Nangona kunjalo, ayizizo zonke iintambo zePP ezisebenza ngokulinganayo kwizixhobo ezizenzekelayo. Ukucaciswa komgangatho womatshini, ukunyamezela okuqinileyo, kunye nokujika okungaguqukiyo kubalulekile ekusebenzeni okuthembekileyo. Esi sikhokelo sichaza ukuba yintoni eyenza umtya wePP ulungele imigca yokupakisha ezenzekelayo kunye nendlela yokukhetha inkcazo echanekileyo.

Ukubotshwa kwe-PP kuhlala kuneengxaki ezinjengokwaphuka ngexesha loxinzelelo, imithwalo iyakhululeka ngokuhamba kwexesha ngenxa yokuba imathiriyeli iyolula, oomatshini bokuqhobosha abazenzekelayo bayaxinga kakhulu, kunye nokomelela kokutywina okungahlali kungatshintshi. Amaxesha amaninzi, ezi ngxaki zibangelwa kukungafani komgangatho
