Kon, taxawal sistem buy saytu kalite bu lalu ci science te sistemik mooy lëkkalekaay bi gëna am solo ngir mëna wóor kalite tub nylon yi.
I. Kontrolu macceer bu bees: Garanti Kalite
Fondaasioŋu kalite tube nylon mingi ci tànneef ak saytu macceer bu bees bi. Nylon (polyamide) resin, muy meceer bi gëna am solo, amna seddaleb diisaay moleculaire, cristallinite, ak ratio additif buy indi jafe-jafe ci màndarga mekanik yi ak bañaale environmaa bi ci tube bi. Bi ci njëkk mooy ñu saytu furnisër yi bu baax, ñu sàkku ci ñoom ñu joxe ay leeral ci macceer yu bees yi méngoo ak sàrti àdduna bi (lu melni ISO 1874-2 wala ASTM D4066). Bépp lotu macceer bu bees dañu ko wara saytu bu baax balaa muy yegsi usin bi, ñu bàyyi seen xel ci saytu màndarga yu am solo yu melni melt flow index (MI), dooley traction, tàngoor distorsion thermique (HDT), ak absorption ndox. Ci misaal, index debit melt bu tub nylon bi ñuy jëfandikoo ci sistem hydraulique yu am pression bu kawe dañu ko wara saytu ci diggante 2-5 g/10min ngir mëna am ekilibre ci digganté fluidité ak dooley produit bi jeex. Tube nylon biñ defaree pajum fàww ñu gëna bàyyi xel ci residu composé organik yu woyof yi (VOC) ak biocompatibilite (lu melni sertifikaasioŋ USP Class VI). Rax ci dolli, barabu dencukaay macceer bu bees bi dañu ko wara saytu bu baax ngir tàngoor ak niir (ñu digal mu néew wala mu tolloo ak 25 degre, niir relatif mu néew wala mu tollu ci 40%) ngir moytu absorption humidité bu mëna indi ay jafe-jafe ci mekanik yi.
II. Xool bu baax parametru procédure production lu am solo la. Li gëna bari ci li ñuy woowe moulage ci tub nylon mooy extrusion, seddal ak forme, ak ginaaw - liggéey (lu melni flaring ak soudure). Deviasioŋ yi ci parametre yi ci bepp etap mën nañu indi jafe-jafe ci kalite bi. Ci jamonoy extrusion, méngoo gaawaayu vis bi, gradient tàngooru baril bi, ak gaawaayu traction lu am solo la: tàngooru baril bi dañu koy def ci 240-280 degre (ñu koy méngale ak xeetu nylon bi); tàngoor wu ëpp mën na indi yàqu-yàqu ci resin bi (di feeñ ci mboq ak mboq ci tube bi), waaye tàngoor wu woyof wu ëpp mën na indi plastisasioŋ bu baaxul (muy jur ondulation ci kaw suuf si wala concentration stress bi ci biir); gaawaayu traksioŋ bi dafa wara méngoo ak viteesu extrusion bi, luko moy dina jur dëgëraay bu tolloowul ci miir bi (muñ lu ëpp ±5% dañu jàpp ni du luñu ko mëna nangu). Ci jamonoy seddal ak defar, tàngooru ndox mi (ñu koy saytu ci 20{12}}40 degre) ak diiru seddal bi dañuy indi jafe-jafe ci stabilite dimensionel bu tube bi. mën na jur stress ci biir, te mën na jur stress buy xar ci diiru jëfandikoo gi ci topp. Ngir tube nylon yuñ jagleel (lu melni yu mëna dékku tàngoor wu metti wala yu mëna dékku wear), fàww ñu yokk ci ay produit yuy dooleel lu melni fibre de verre ak nanotube carbone ci diiru liggéey bi. Su demee nii, fàww ñu saytu bu baax njaxas mi ngir moytu wuute ci liggéey bi.
Ⅲ. Construction of a Full-Process Inspection System Quality control needs to be implemented throughout the entire chain from raw materials to semi-finished products to finished products, using multi-dimensional inspection methods to achieve defect interception and performance verification. For online inspection, the production line needs to be equipped with real-time monitoring equipment. For example, an infrared spectrometer can be used to monitor the uniformity of raw material mixing, and a laser diameter gauge (accuracy ±0.01mm) can be used to dynamically detect the outer diameter and wall thickness of pipes. A visual recognition system can then automatically remove surface scratches, bubbles, or impurity particles (defects >0.1mm war nañu ko màrkee). Test yiñ def ci net bi dañuy tënk ñatti wàll yu mag: màndarga mekanik, dayo chimik, ak mëna ànd ak environmaa bi. Test mekanik yi dañuy àndaale ak dooley traction ( lu ëpp wala lu tollu ci 40MPa ni standard biñ nangu), pression buy toj (3-5 yoon pression biy liggéey), ak test coono buy ñaw (10,000 cycle te du xar). Test chimik dafay nuru anam yu metti, lu melni suul tub nylon ci biir asid wala alkaline (pH 2-12) wala essence ci diiru 72 waxtu, test coppite diisaay ( Lu néew wala tollu ci 1%) ak stabilite dimensionel. Test yiñ def ci environmaa bi dañuy àndaale ak tàngoor wu yéeg wala wu wàcci (-40 degre ba 120 degre, 5 yoon), màgget ultraviolet (tegu dooley traction lu ëpp wala lu tollu ci 80% ginaaw 1000 waxtu irradiation UV), ak jàngat résistance diw ak SAE (compli0).
IV. Jàppale ci lëkkaloo ak liggéeykat yi ak sistemu njiit yi Kontrôlu kalite bu baax mingi aju ci liggéey buñ yamale ak jumtukaayu toppu wareef. Liggéeyukaay yi war nañu defar ay sàrti liggéey yu leer (SOPs) yu leer ci anam yi ñuy jëfandikoo, bariwaayu saytu, ak anam yi ñuy jëfandikoo bu jaarul yoon ci bépp liggéey (ci misaal, su tàngooru extruder bi soppeekoo lu ëpp ± 5 degre, masin bi dafa wara taxaw ngir xool ndax sistem biy doxal tàngoor bi wala tàngoor wi).
