Amathiphu okuthenga utshani bokwenziwa 1: usilika wotshani
1. Izinto zokusetshenziswa Izinto zokusetshenziswa zotshani bokwenziwa ikakhulukazi yi-polyethylene (PE), i-polypropylene (PP) kanye ne-nylon (PA)
1. I-Polyethylene: Izwakala ithambile, futhi ukubukeka kwayo kanye nokusebenza kwayo kwezemidlalo kuseduze notshani bemvelo. Yamukelwa kabanzi ngabasebenzisi futhi isetshenziswa kabanzi emakethe.
2. I-Polypropylene: I-fibre yotshani iqinile futhi i-fibrillated kalula. Ngokuvamile isetshenziswa ezinkundleni zethenisi, ezinkundleni zokudlala, ezinkundleni zezindiza noma ekuhlobiseni, futhi ukumelana kwayo nokuguguleka kubi kancane kune-polyethylene.
3. Inayiloni: Yinto yokuqala eluhlaza yefayibha yotshani yokwenziwa futhi iyinto engcono kakhulu eluhlaza. Amazwe athuthukile njenge-United States asebenzisa kakhulu utshani benayiloni.
Amathiphu okuthenga utshani bokwenziwa2: Ngaphansi
1. Iphansi elilukiwe le-PP loboya obuhlanganisiwe: eliqinile, elisebenza kahle ekulweni nokugqwala, linamathela kahle kakhulu ku-glue kanye notshani, kulula ukuguga, futhi intengo iphindwe kathathu kunendwangu elukiwe ye-PP.
2. Iphansi elilukiwe le-PP: ukusebenza okujwayelekile, amandla okubopha abuthakathaka
Iphansi lefayibha yengilazi (iphansi legridi): Ukusetshenziswa kwefayibha yengilazi nezinye izinto kungasiza ekwandiseni amandla ephansi kanye namandla okubopha kwefayibha yotshani.
3. Iphansi le-PU: umsebenzi oqinile kakhulu wokulwa nokuguga, ohlala isikhathi eside; ukunamathela okuqinile emgqeni wotshani, futhi okunobungani nemvelo futhi akunaphunga, kodwa izindleko ziphezulu, ikakhulukazi iglue ye-PU engenisiwe ibiza kakhulu.
4. Iphansi elilukiwe: Iphansi elilukiwe alisebenzisi inhlaka engemuva ukuze linamathele ngqo empandeni yefayibha. Leli phansi lingenza inqubo yokukhiqiza ibe lula, ligcine izinto zokusetshenziswa, futhi ezintweni ezibalulekile, lingahlangabezana nemidlalo evinjelwe utshani obujwayelekile bokwenziwa.
Amathiphu amathathu okuthenga utshani bokwenziwa: iglue
1. I-Butadiene latex iyinto evamile emakethe yotshani bokwenziwa, esebenza kahle, ishibhile, futhi incibilika emanzini.
2. Iglue ye-polyurethane (PU) iyinto esetshenziswa emhlabeni wonke. Amandla ayo okubopha aphindwe kaningana kune-butadiene latex. Ihlala isikhathi eside, inombala omuhle, ayigqwali futhi ayikhuli, futhi inobungani nemvelo, kodwa intengo ibiza kakhulu, futhi isabelo sayo semakethe ezweni lakithi siphansi kakhulu.
Amathiphu okuthenga utshani bokwenziwa 4: Ukwahlulela ngesakhiwo somkhiqizo
1. Ukubukeka: umbala ogqamile, izithombo zotshani ezijwayelekile, ukugoba okufanayo, isikhala senaliti esifanayo ngaphandle kokuthunga okweqiwe, ukuqina okuhle; ukufana okuphelele nokuba yisicaba, akukho mehluko ocacile wombala; inhlaka ephakathi esetshenziswe phansi futhi yangena ngemuva, akukho ukuvuza noma umonakalo wenhlaka.
2. Ubude botshani obujwayelekile: Empeleni, uma inkundla yebhola inde, kungcono (ngaphandle kwezindawo zokuzilibazisa). Utshani obude bamanje bungu-60mm, obusetshenziswa kakhulu ezinkundleni zebhola. Ubude botshani obuvamile obusetshenziswa ezinkundleni zebhola bungu-30-50mm.
3. Ubuningi botshani:
Hlola ngezindlela ezimbili:
(1) Bheka inani lezinaliti zotshani ezingemuva kwengadi. Uma izinaliti ziningi ngemitha ngayinye yotshani, kungcono.
(2) Bheka izikhala zemigqa kusukela ngemuva kotshani, okungukuthi, izikhala zemigqa yotshani. Uma izikhala zemigqa ziminyene, kungcono.
4. Ubuningi befayibha yotshani kanye nobubanzi befayibha yefayibha. Izindwangu zotshani zezemidlalo ezivamile ziyi-5700, 7600, 8800 kanye ne-10000, okusho ukuthi uma ubukhulu befayibha yentambo yotshani buphakeme, ikhwalithi iba ngcono. Uma izimpande eziningi eqenjini ngalinye lezindwangu zotshani, kulapho intambo yotshani iba ncane khona futhi ikhwalithi iba ngcono. Ububanzi befayibha bubalwa ku-μm (micrometer), ngokuvamile phakathi kuka-50-150μm. Uma ububanzi befayibha bukhulu, kuba ngcono. Uma ububanzi bukhulu, kuba ngcono. Uma ububanzi bukhulu, kulapho intambo yotshani iqine khona futhi imelana nokuguguleka. Uma ububanzi befayibha buncane, kufana kakhulu nephepha lepulasitiki elincane, elingamelani nokuguguleka. Inkomba yefayibha ngokuvamile kunzima ukuyilinganisa, ngakho-ke i-FIFA ngokuvamile isebenzisa inkomba yesisindo sefayibha.
5. Ikhwalithi yefayibha: Uma isisindo sobude beyunithi efanayo sikhulu, kulapho intambo yotshani iba ngcono khona. Isisindo sentambo yotshani silinganiswa ngobuningi befayibha, esivezwa ku-Dtex, futhi sichazwa njenge-1 gram ngamamitha ayi-10,000 efayibha, ebizwa ngokuthi i-1Dtex.Uma isisindo sentambo yotshani sikhulu, uma intambo yotshani ijiyile, isisindo sentambo yotshani sikhulu, ukumelana nokuguguleka kuqina, futhi uma isisindo sentambo yotshani sikhulu, isikhathi senkonzo siba side. Njengoba intambo yotshani isinda, izindleko ziphakeme, kubalulekile ukukhetha isisindo sotshani esifanele ngokweminyaka yabadlali kanye nokusetshenziswa kaningi. Ezindaweni ezinkulu zemidlalo, kunconywa ukusebenzisa utshani olulukiwe ngentambo yotshani enesisindo esingaphezu kuka-11000 Dtex.
