Kenyelletso ea Sehlahisoa
Liatlana tsa matsoho tse telele tsa bongaka ba liphoofolo tse lahloang li etselitsoe tšebeliso ea lekhulo ka ho khetheha, tse entsoeng ka 60% polyethylene vinyl acetate copolymer (EVA) le 40% polyethylene (PE). Lintlha tse latelang li tla hlalosa sehlahisoa ka ho qaqileng mabapi le litšobotsi tsa thepa, ho tšoarella ha li-glove, ho fetoha ha maemo le ho sireletsa tikoloho. Pele ho tsohle, thepa ea 60% EVA + 40% PE e etsa hore glove ena e be le bonolo bo botle le elasticity. Lisebelisoa tsa EVA ke thepa ea maiketsetso e nang le bonolo bo botle le elasticity, e ka etsang hore glove e lekane letsoho hantle, e eketsa matšeliso le ho fana ka mokhoa o molemo oa ho sebetsa. Thepa ea PE ke polima e nang le elasticity e ntle le ductility, e etsang hore liatlana li tšoarelle le ho tiea. Motsoako ona oa lisebelisoa o etsa hore glove e be bonolo le e tšoarellang.
Taba ea bobeli, liatlana tse entsoeng ka thepa ena li na le nako e ntle ea nako e telele. Kaha ts'ebetso ea mapolasi e hloka ho kopana le liphoofolo, liatlana li hloka ho hana ho hobosoa le ho taboha. Motsoako oa EVA le PE o etsa hore liatlana li hanyetse matla a kantle joalo ka ho hopa, ho hula le ho ferekana, le ho lelefatsa bophelo ba ts'ebeletso. Ka tsela ena, basebetsi ba mapolasi ba sebelisang liatlana tsena ba ka sebetsa ka mokhoa o bolokehileng nako e telele, 'me ka nako e ts'oanang ba fokotsa sekhahla sa phetisetso ea liatlana le ho ntlafatsa katleho ea mosebetsi. Ho phaella moo, thepa ea glove ena e boetse e na le tekanyo e itseng ea tšireletso ea tikoloho. EVA ke thepa e bolokang tikoloho e se nang lintho tse kotsi 'meleng oa motho mme e ka fokotsa ka katleho kotsi ea tšilafalo ea tikoloho. PE ke thepa e ka sebelisoang hape ka mor'a ho sebelisoa, ho fokotsa tšebeliso ea lisebelisoa tsa tlhaho le khatello ea tikoloho. Ka hona, ts'ebeliso ea 60% EVA + 40% PE e lahloang liatlana tsa letsoho tse telele tsa liphoofolo li ke ke tsa sireletsa matsoho a lingaka tsa liphoofolo kapa basebetsi ba ranch feela, empa hape li baka tšusumetso e fokolang tikolohong, e tsamaellanang le mohopolo oa nts'etsopele e tsitsitseng. Ho akaretsa, tlelafo ena e telele ea matsoho ea bongaka ba liphoofolo e entsoe ka 60% EVA+40% ea thepa ea PE. E na le bonolo bo botle le elasticity, e lelefatsa bophelo ba tšebeletso, hape e na le tekanyo e itseng ea tšireletso ea tikoloho. Likarolo tsena li etsa hore tlelafo ena e be khetho e nepahetseng lits'ebetsong tsa mapolasi, e fana ka boiphihlelo bo betere ba ts'ebetso bakeng sa basebetsi ba mapolasi.
