Phambi kokuba ilungele ukubetha ezishelfini, iteyiphu yokupakisha kufuneka iphumelele uthotho lweemvavanyo eziqatha ukuqinisekisa ukuba inokuhlangabezana neemfuno zomsebenzi ebiyilelwe kwaye igcine ubambe olomeleleyo ngaphandle kokusilela.

Iindlela ezininzi zovavanyo zikhona, kodwa iindlela zovavanyo eziphambili zenziwa ngexesha loVavanyo lwePhysical Testing kunye ne-Application Testing process yeeteyiphu.

Uvavanyo lomsebenzi we-tape yokupakisha lulawulwa yiBhunga le-Pressure Sensitive Tape Council (PSTC) kunye ne-American Society of Testing and Materials (ASTM).Le mibutho ibeka imigangatho yovavanyo lomgangatho kubenzi beeteyiphu.

Uvavanyo lomzimba luvavanya iimpawu zeteyiphu ezibonakalayo ze-peel, tack kunye ne-sheer - iimpawu ezintathu ezilungelelanisiweyo ukuvelisa iteyiphu yokupakisha esemgangathweni.Ezinye zezi mvavanyo ziquka:

• Ukuncamathela kwintsimbi engatyiwa:ilinganisa inani lamandla athathayo ukususa i-tape kwi-substrate yensimbi engenasici.Nangona i-tape yokupakisha ayinakwenzeka ukuba isetyenziswe kwinsimbi engenasici, ukuvavanywa kwesi sixhobo kunceda ukucacisa iimpawu zokubambelela kwi-tape kwi-substrate ehambelanayo.
• Ukuncamathela kwiFiberboard:ilinganisa ubungakanani bamandla afunekayo ukususa iteyiphu kwi-fiberboard - izinto ezinokuthi zisetyenziswe kakhulu kwisicelo sayo.
• Amandla okucheba/Ukubamba Amandla:umlinganiselo wesakhono sokuncamathelisa ukuxhathisa ukutyibilika.Oku kubalulekile kwizicelo zokutywinwa kweekhathoni njengoko iithebhu zeteyiphu ziphantsi kwamandla rhoqo ukusuka kwimemori kwiiflephu ezinkulu zebhokisi, ezinotyekelo lokufuna ukubuyela kwindawo ethe tye.
• Tensile strength: umlinganiselo womthwalo onokuthi uxhaso lukwazi ukuwuthwala ukuya kuthi ga kwindawo yawo yokuphuka.Iteyiphu ivavanyelwa amandla okuqina kuwo omabini amacala anqamlezayo kunye nobude, okuthetha kububanzi beteyiphu nakubude beteyiphu, ngokulandelelanayo.
• Elongation: ipesenti yokwelula eyenzeka de kufike indawo yokuqhawuka kweteyiphu.Ukwenza ngcono iteyiphu, ubude kunye namandla okuqina kufuneka alungelelaniswe.Awuyi kufuna iteyiphu eyolule kakhulu, okanye engolukiyo kwaphela.
• Ukutyeba: ekwabizwa ngokuba yigeyiji yeteyiphu, lo mlinganiselo udibanisa ubunzima bedyasi encamathelayo kunye nobukhulu bezinto ezixhasayo zeteyiphu ukuvelisa umlinganiselo ochanekileyo wobunzima beteyiphu ngokubanzi.Amabanga aphakamileyo eteyiphu anenkxaso etyebileyo kunye nobunzima bedyasi encamathelayo enzima kwizicelo ezinzima.

Uvavanyo lwesicelo lunokwahluka phakathi kwabavelisi, kwaye lunokwenziwa ngokwezifiso ukuze lulungele usetyenziso olucetywayo lweentlobo ezahlukeneyo zeeteyiphu.

Ukongeza kuvavanyo lweenkcukacha zemveliso, iiteyiphu zokupakisha ziyavavanywa ukuze kubonwe ukuba zihamba kakuhle kangakanani na kuhambo.I-International Safe Transit Authority (ISTA) ilawula ezi ntlobo zovavanyo, ezihlala zibandakanya iimvavanyo zokuhla, uvavanyo lokungcangcazela olulinganisa ukuhamba kwemveliso kwilori, ubushushu kunye novavanyo lokufuma ukufumanisa ukuba iteyiphu kunye nokupakishwa kwayo kubambe kangakanani kwiindawo ezingenamqathango. , kunye nokuninzi.Oku kubaluleke kakhulu kuba ukuba iteyiphu ayikwazi ukusinda kwikhonkco lokubonelela, akukhathaliseki ukuba ibinokwenza kakuhle kangakanani kumgca wokupakisha.

Nokuba loluphi na uhlobo lweteyiphu yokupakisha oyidingayo kwisicelo sakho, unokuqiniseka ukuba ivavanyiwe ukuqinisekisa ukuba imelana namabango omgangatho womenzi kunye nemigangatho yePSTC/ASTM abaphantsi kwayo.
