Iimfuno zemihla ngemihla ezifana nokutya nezinto zendlu ziyimfuneko kubomi bemihla ngemihla babantu. Njengoko ubomi buqhubeka ngokukhawuleza, ukutya okupakishiweyo ezahlukahlukeneyo nezinto eziyimfuneko zemihla ngemihla ziye zazalisa iivenkile ezinkulu nakwiivenkile ezinkulu, nto leyo eyenza kube lula ukuba abantu bazithenge, bazigcine baze bazisebenzise ezi zinto. Izinto zokupakisha zidlala indima ebalulekileyo kolu ncedo. Ngophuhliso oluqhubekayo lweshishini lokupakisha, imigca yemveliso yokupakisha ngokuzenzekelayo isetyenziswa kakhulu kwimveliso yokutya kunye neemfuno zemihla ngemihla. Njengoko isantya kunye nokuzenzekelayo koomatshini bokupakisha kuqhubeka nokunyuka, imiba yomgangatho nayo iye yabonakala. Iingxaki ezinjengokophuka kwefilimu, ukutyibilika, ukuphazamiseka komgca wemveliso, kunye nokuvuza kwepakeji kuya kusiba rhoqo, okubangela ilahleko enkulu kubavelisi bezinto zokupakisha eziguquguqukayo kunye neenkampani zoshicilelo. Esona sizathu sisekungakwazini ukulawula ukungqubana nokutywinwa kobushushu kwiifilimu zokupakisha ngokuzenzekelayo.
Okwangoku, iifilimu zokupakisha ezizenzekelayo kwimarike zineziphene eziphambili zilandelayo:
- Uluhlu lwangaphandle lwefilimu yokupakisha lune-coefficient ephantsi ye-friction (i-COF), ngelixa i-layer yangaphakathi ine-COF ephezulu, ebangela i-slippage ngexesha lefilimu eqhutywe kumgca wokupakisha.
- Ifilimu yokupakisha iqhuba kakuhle kumaqondo obushushu aphantsi kodwa ifumana imiba kumaqondo obushushu aphezulu ngexesha lenkqubo yokupakisha ngokuzenzekelayo.
- I-COF ephantsi yomaleko wangaphakathi inqanda ukubekwa ngokufanelekileyo kweziqulatho ngaphakathi kwefilimu yokupakisha, ekhokelela ekungaphumelelini kokutywinwa xa umtya wetywina lobushushu ucinezela imixholo.
- Ifilimu yokupakisha iqhuba kakuhle ngesantya esiphantsi kodwa ifumana ukutywinwa kobushushu obuhlwempuzekileyo kunye nemiba yokuvuza njengoko isantya somgca wokupakisha sikhula.
Ngaba uyayiqonda iI-COFyefilimu yokupakisha ngokuzenzekelayo? Eqhelekileyoanti-blocking kunye ne-slip agentskunye nemingeni
I-COF ilinganisa iimpawu zokutyibilika zezinto zokupakisha. Ukuguda komphezulu wefilimu kunye ne-COF efanelekileyo zibalulekile kwinkqubo yokupakishwa kwefilimu, kunye neemveliso zemathiriyeli zokupakisha ezahlukeneyo ezineemfuno zeCOF ezahlukeneyo. Kwiinkqubo ezichanekileyo zokupakisha, ukukhuhlana kunokusebenza njengamandla okuqhuba kunye nokuxhathisa, okudinga ulawulo olusebenzayo lwe-COF ngaphakathi koluhlu olufanelekileyo. Ngokubanzi, iifilimu zokupakisha ezizenzekelayo zifuna i-COF ephantsi ngokwentelekiso kumaleko angaphakathi kunye neCOF ephakathi kumaleko angaphandle. Ukuba i-COF yangaphakathi iphantsi kakhulu, inokubangela ukungazinzi kunye nokungahambi kakuhle ngexesha lokwenziwa kwengxowa. Ngakolunye uhlangothi, ukuba umaleko wangaphandle we-COF uphezulu kakhulu, unokubangela ukuchasana okugqithisileyo ngexesha lokupakishwa, okukhokelela kuguquko lwezinto eziphathekayo, ngelixa i-COF ephantsi kakhulu inokubangela ukutyibilika, kubangele umkhondo kunye nokusika okungachanekanga.
I-COF yeefilimu ezidibeneyo ithonywa ngumxholo we-anti-blocking kunye ne-slip agents kwi-layer yangaphakathi, kunye nokuqina kwefilimu kunye nokugudiswa. Okwangoku, ii-agent ezityibilikayo ezisetyenziswa kumaleko angaphakathi ziqhelekile ziikhompawundi ze-asidi ye-amide enamafutha (njengee-amides eziphambili, ii-amides zesibini, kunye ne-bisamides). Ezi zixhobo azinakunyibilika ngokupheleleyo kwiipolymers kwaye zivame ukufudukela kumphezulu wefilimu, ukunciphisa ukungqubuzana komhlaba. Nangona kunjalo, ukufuduka kwe-amide slip agents kwiifilimu ze-polymer kuchatshazelwa zizinto ezahlukeneyo, kubandakanya ukugxininiswa kwe-agent, ubukhulu befilimu, uhlobo lwe-resin, ukuxinezeleka komoya, indawo yokugcina, ukusetyenzwa ezantsi, iimeko zokusetyenziswa, kunye nezinye izongezo, okwenza kube nzima ukuqinisekisa ukuba uzinzile. I-COF. Ngaphezu koko, njengoko iipolima ezininzi zilungiswa kumaqondo obushushu aphezulu, ukuzinza kwe-thermal oxidative yee-agent ezityibilikayo kuya kubaluleke ngakumbi. Ukuthotywa kwe-oxidative kunokukhokelela ekulahlekelweni kokusebenza kwe-ejenti ye-slip, i-discoloration, kunye nevumba.
Ezona zixhobo zixhaphakileyo zokutyibilika ezisetyenziswa kwi-polyolefins zii-amide ezinamafutha e-long-chain, ukusuka kwi-oleamide ukuya kwi-erucamide. Ukusebenza kwee-ejenti ze-slip kubangelwa ukukwazi kwabo ukukhupha ifilimu kwifilimu emva kwe-extrusion. Iiarhente zokutyibilika ezahlukeneyo zibonisa amaxabiso awohlukeneyo emvula yomhlaba kunye nokunciphisa iCOF. Njengoko i-amide slip agents ziyi-low-molecular-weight migratory slip agents, ukufuduka kwabo ngaphakathi kwefilimu kuphenjelelwa zizinto ezahlukeneyo, ezikhokelela kwi-COF engazinzanga. Kwiinkqubo ze-lamination ezinganyibilikiyo, ii-amide slip agents ezigqithisileyo kwifilim zinokubangela imiba yokutywinwa kobushushu, edla ngokubizwa ngokuba "kukuvimba." Inkqubo ibandakanya ukufuduka kwe-isocyanate monomers yamahhala kwi-adhesive kumphezulu wefilimu, isabela nge-amide ukwenza i-urea. Ngenxa yeqondo eliphezulu lokunyibilika kwe-urea, oku kubangela ukuba kuncitshiswe ukusebenza kokutywinwa kobushushu kwefilimu elaminethiweyo.
Ni-oveli non-ezifudukayo super slip&Anti-blockingiarhente
Ukuhlangabezana nale miba, iSILIKE iye yasungula I-Super-slip engavuthiyo kunye ne-Anti-blocking ye-Masterbatch Additive-Inxalenye yochungechunge lwe-SILIMER. Ezi mveliso zepolysiloxane eziguquliweyo ziqulathe amaqela asebenzayo asebenzayo. Iimolekyuli zabo zibandakanya zombini iisegment ze-polysiloxane chain kunye ne-carbon chain chain kunye namaqela asebenzayo. Iintambo zekhabhoni ezinde zamaqela asebenzayo asebenzayo angakwazi ukuxhamla ngokomzimba okanye ngokwekhemikhali kunye nesiseko se-resin, i-anchoring i-molecule kunye nokufezekisa ukufuduka lula ngaphandle kwemvula. I-polysiloxane chain segments kwi-surface ibonelela ngempembelelo egudileyo.
