Ukuziphatha Kwemithambo Yokuqonda Nokuziphatha Kwezinkulungwane Zokusebenza
Ukuphepha kwemithambo yokuqonda kuyisibonelo sokuthi kuyasebenza njani kumasevisi amaningi. Kusimahla sesikhombisa esikhombisa kwezinkulungwane zokusebenza, ukuziphatha kwezinkulungwane zokuphepha nokuziphatha kwezinkulungwane zokusebenza kufuna ukuthi isipholo sonke sifanele kubizo laba bafanele.
Ukuziphatha Kwemithambo Emibili: Ukulinganisa, Ukulinganisa Kwesikrini, Nokuziphatha Kwezinkulungwane Zokuphepha
Ukubala—ukubhala kwesikhala—kuqondwa ngemithameteri yelazeri esihlakazini isikhala esihambayo kusukela ku-1,000 ukubala ngosekholeni, kufunda izilinganiso ezincane njengoko ziyi ±0.005 mm. I-Denier (umbungo wemasi ngama-gramu ngama-9,000 amitha) iqondwa kusuka kumkhawulo wokubhala okuphelele nokude; kuyilandelwa ngqo ngokubili kwezinhlobo zokubhala futhi kufanele ibe phakathi kwe-2% yokubhala okuzidingekile ukuze kuvunyelwe ukubaluleka kokubhala nokubhala kwezinyathelo. Ukuqonda kwezinhlobo zokubhala—ukukhula okukhulu kabusha emva kokugqibela—kuqondwa ngokusebenzisa i-ASTM D2256 kusuka kumashini okuziqonda konke. Izinhlobo zokubhala eziphakeme kusukela ku-8–10 g/denier, nezinhlobo zokubhala zokugqibela phakathi kwe-15% kanye ne-30%. Ngokujabulisa, lezi zimbili zizindlela zokubaluleka kwezinhlobo zokubhala ngoba ziyilandelwa ngqo kuzinyathelo zokubhala, zokubhala kanye nezinyathelo zokubhala kwezinhlobo zokubhala.
Izivivinyo zokubaluleka kakhulu: Ukubhala kwezinkundla, Ukubhala kwezinhlobo zokubhala, kanye nokubaluleka kwe-UV
Ukuqondisa kwesixhobo sokugcina—kubhalwa ngokuthatha isixhobo sokugcina esingaphansi kwezinye izinto—kubhekisana nge-50–70% yokuqondisa kokuphakama kwezinye izinto, kubonisa ukuthi isixhobo sokugcina sisebenza njani ekupheleni kwezinye izinto kwe-mesh nezinhlobo zezincwadi. Ukugcina kwezintambo kubhalwa ngokuthi kubhekelwa umgqa wokuphakama kwezinye izinto kwi-150°C ngemizuzu e-15; ukusebenza okuhle kudinga ukuthi ukugcina kwezintambo kungafana nangaphezu kwe-2% ukugcina kwezintambo kwezinhlobo zezincwadi ezihlukene. Ukusetyenziswa kwe-UV kubhalwa ngokusebenzisa ukuzilahla kwezinye izinto kwi-QUV chamber ngezilampu ze-UVA-340 nezinkqubo zokugcina; emva kwezikhathi eziyisigidi, ukuphakama okugcinwe kufanele kube kude kwe-85% ukuze kubonakaliswe ukuthi kuyasebenza kwezinye izinto kwezindawo zezinkqubo zezinye izinto. Lezi zizifundo zizonke zibonisa ukuthi isixhobo sokugcina siyasebenza kakhulu kwezinye izinto zezinkqubo zezinye izinto, kwezinkqubo zezintambo, nezinkqubo zezinye izinto.
Ukukhokhela Kwempilo Kwezinhlobo Zokusebenza Kwesixhobo Sokugcina Sokusebenza Kwezinhlobo
Ukukhokhela kwempilo kwezinhlobo zokusebenza kwezixhobo sokugcina kuyisikhuba esisodwa—kusuka kwezinhlobo zokufika kwezinhlobo zokusebenza kuya kwezinhlobo zokugcina kwezinhlobo zokugcina. Ukukhokhela okuphelele kuzo zonke izikhathi kuzoba yinkqubo yokugcina kwezinhlobo zokusebenza nokunciphisa izinhlobo zezinhlobo zokugcina.
Ukubuka Kwemithambo Yekhupholi yokuNgezwa kanye Nezibonakaliso Zokuvavanya Ukuthi Ikhupholi Iyathola Ngokufanayo
Ikhupholi yonke isebenza ngokuzimisa kakhulu kabefore ukuthi ishwe. Ukuthola kwemithambo yekhupholi (MFI) kuyizindaba zokuthola ngokusebenzisa i-ASTM D1238 ukuze kubonakaliswe ukuthi ubunzima bawo buyafanana nobude obuncane obudingekile ukuthi ishwe ngokusobala. Ubukhulu bekhwama kuyizindaba zokuthola ngokusebenzisa i-Karl Fischer titration noma ukuthola ukungcoliswa kwenqubo; ukuthi kuphela 0.02% yokukhula kwekhupholi yasepolyamide kungahlela ukuthi ikhupholi ishwe ngokufa kwezinto ezinamandla kanye nokuphepha ukuthi kubhekise kumthambo wokushweleka ngokuphepha kuhlu kwe-15% [Izindaba zokusebenza, 2022]. Izinkulungwane zezinkampani—kubanzi izinkampani zokuvavanya ukuthi kungabi khona ukuthi kubhekise kumthambo wokushweleka, izinkampani zokubhala, kanye nezinkampani zokuphatha—ziyavavanywa ngokusebenzisa i-gravimetric noma i-spectroscopic ukuze kubonakaliswe ukuthi izinkulungwane ziyafanana. I-capillary rheometer iyasebenzisa izimo zokushweleka ukuze kubonakaliswe ukuthi kukhona ukuthola ukuthi kunezinkinga zokushweleka phakathi kwezinkulungwane. Zonke izindaba zokungezwa ziyabhalwa kwi-laboratory information management system (LIMS), ekwenzeni indlela yedijithali eyalibona ukuthi izincike zomthambo wokungezwa ziyahlakisa kumthambo wokushweleka wokuphatha umthambo wokushweleka.
Ukugcina ukuziphatha kwe-Monofilament: Ukuphakanyiswa kwezindawo, Ukubona amaphutha esikhwama, nokufunda indawo yebhethi
Emva kusukela kwe-quenching ne-drawing, umonofilament uphuma ngaphandle kwezindawo zokuhlola zokuzenzakalelayo. Amicrometers e-laser angamabili noma amathathu aphatha izindlela zokubala ngokupheleleyo ngokulingana ne-±0.005 mm; ukungalingani kuyavula amazwi okuhlanza ngokushesha nokuthiwa ngokuzenzakalelayo ngokuzenzakalelayo ngokulingana ne-2023 industry standard. Amakhamera e-optical aphezulu kokushaya aphinda aphinda akhanyisa umkhakha ngokushesha kakhulu kwe-300 m/min, akhanyisa izinkinga zomkhakha—kodwa kufuneka kubhekwe izinkinga zokugcina, izinkinga zokugcina, nokuguqula kancane—okukhulu kakhulu kwe-0.01 mm². Emizini yezindawo ezihlakanipileyo, lokhu kunciphisa izinkinga ngapansi kwe-50 ppm. Isipooli sonke sifuna isibarcode esisodwa esilinkisiwe nge-lot yepolimer, izindlela zokusukela, nokuthi kuyiwe yisiqu—kukhomba ukuthi kungafikiwa ngokupheleleyo ukuthola indlela yokuvula izinkinga futhi ukuthi kufanele kubhekwe i-ISO 9001. Izicharti zokubala izindlela zokusebenza (SPC) zibhabha izindlela ezikhulu njenge-variation yezindlela zokubamba, okwesikhundla esikhulu kuyabhabha ngapansi kwe-5% emaqembini onke [Industry data, 2023], kunciphisa ukusebenza kwabantu kanye nokuthi kubhekwe ukuthi izishiyelo ziyisodwa ngokupheleleyo.
