Kumgca wokupakisha ohamba ngokukhawuleza, i-heat sealer yi-bottleneck. Ngalo lonke ixesha iplastiki etyhidiweyo incamathela kwimela yokutywina, umgca uyayeka ukukhuhla - ukubulala imveliso. Lonke itywina elibi lithumela iingxowa ukuze ziphinde zisebenze. Yonke into enxitywayo yokutywina ibiza amawaka-waka ukuyibuyisela.
Isisombululo silula ngokukhohlisa: sebenzisa Iteyiphu ye-PTFE yobushushu obuphezulu ukuya kumphezulu wokutywina. Lo maleko omncinci we-PTFE-coated fiberglass, kunye ne-adhesive ye-silicone yobushushu obuphezulu, uguqula inkqubo yokutywinwa kobushushu.
I-Aokai PTFE ibonelele ngeteyiphu ye-PTFE kubavelisi bezixhobo zokupakisha kunye nabasebenzisi bokugqibela iminyaka. Eli nqaku libandakanya amaxabiso ezicelo ezingundoqo ezine - ukukhutshwa kwe-anti-stick, ukukhuselwa kwezixhobo, umgangatho wokutywinwa, kunye nokukhuhlana okuphantsi - kunye neendlela zokukhetha eziphambili (i-substrate, ubushushu, i-adhesive, i-mechanical properties) ukukunceda ukhethe i-tape efanelekileyo kumgca wakho wokutywina.
IiNqobo ezine zeSicelo ezingundoqo ze-PTFE Tape ekutywinweni koBubushushu
1. Ukuphelisa i-Adhesive Residue - iMveliso eqhubekayo yokuSebenza ngokuPhezulu
Le yeyona nzuzo ngqo ye tape ye-PTFE. Iifilimu zokupakisha ezibandakanya i-PE, i-PP, i-PET, kunye neefilimu ezihlanganisiweyo ze-aluminium zivame ukuthamba kwaye zinamathele kwiindawo zokutywina zentsimbi ezingenanto phantsi kobushushu, okubangela ukugqabhuka kwengxowa, ukukrazuka kwefilimu, kunye nexesha eliqhelekileyo lokucoca.
Inceda njani i-PTFE: Amandla omphezulu asezantsi kakhulu (18-20 dynes/cm) agxotha iiplastiki ezinyibilikisiweyo kunye nezinto zokuncamathelisa ezinyibilikayo ezishushu. Ifilimu ikhupha ngokucocekileyo yonke imijikelo.
Isiphumo: Ukwala ukwehla kwezinga; ixesha lokumisa umatshini wokucoca liyancipha ngama-80-90%.
2. Khusela i-Heat-Seal Components - Yandisa uBomi beZixhobo
Ummese wokutywina okanye ibha yokufudumeza yinxalenye yentsimbi echanekileyo. Ngokuhamba kwexesha, ukungqubana kweefilimu kunye neencakuba zokusika kuyayithoba, kwaye i-oxidation / i-corrosion ibeka umphezulu.
I-PTFE njengomaleko okhuselayo osetyenziswayo: I-tape isebenza njengexabiso eliphantsi, elinokutshintshwa. Ukutshintsha iteyiphu kuthatha imizuzu kwaye kubiza iipeni xa kuthelekiswa nokulungisa okanye ukubuyisela ukutywinwa okulungiselelweyo ($500-$5,000+).
Isiphumo: Ubomi benkonzo yezixhobo bunwebeka kakhulu; Izithuba zokutshintshwa zifa zinde.
3. I-Homogenize Ukusasazwa kobushushu-Phucula ukuNxibelelana kweTywina
Iteyiphu ye-PTFE eyomeleziweyo ye-fiberglass ine-cushioning ephakathi kunye neempawu zokusasazwa kwe-thermal. Ihlawulela ukungalingani okuncinci phakathi kwemela yokutywina kunye nefilimu yokupakisha kwinqanaba elincinci.
Indlela esebenza ngayo: Iteyiphu isasaza zombini ubushushu kunye noxinzelelo ngokulinganayo kwindawo yokutywina.
Isiphumo: Amatywina acocekileyo, angaguquguqukiyo anamandla afanayo - akukho zitywina ezingaphelelanga (ukuvuza) okanye ukutshisa kakhulu (imingxuma yeepini).
4. I-Lower Friction Coefficient - Ukuhanjiswa kweFilimu eSmooth
I-PTFE ye-ultra-low kinetic friction coefficient (μ≈0.05-0.10) ixabisekile ngaphaya kwebar yokutywina. Isetyenziswa ngokubanzi ekwenzeni iikhola kunye nemikhono yetyhubhu yeefom ze-vertical fill seal (VFFS) koomatshini.
Iinzuzo: Yehlisa ukuxhathisa ukusebenza kwefilimu yokupakisha; kuthintela ifilim ukolula deformation; kunciphisa ukwakheka okumileyo (xa ibakala elichasayo lisetyenziswa).
Isiphumo: Ukutya kwefilimu okuzinzileyo, iijam ezimbalwa.
I-Aokai PTFE ibonelela nge-fiberglass-backed tape ye-PTFE ngokukodwa kwizicelo zokutywinwa kobushushu. I-silicone yethu ye-PSA idityanisiwe kwinkonzo eqhubekayo ye-260 ° C, iqinisekiswe yi-1,000 yeyure yovavanyo lokuguga kobushushu ngaphandle kokuncamathisela. Ibakala elimnyama elichasene ne-static (ukumelana nomphezulu 10⁶-10⁹ Ω) iyafumaneka kwimigca yefilimu enesantya esiphezulu.
Iimeko zokutywinwa kobushushu ziyahluka kakhulu kubushushu bokusebenza, amandla oxinzelelo, kunye nesantya sokubaleka. Le ngcaciso ilandelayo kufuneka iqinisekiswe ngexesha lokhetho.
