Dab tsi yog cov khoom siv los ua Lub Hnab Spout Environmentally Friendly Thiab Non-toxic?

Tam sim no nws yog nrov heev nyob rau hauv kev ua lag luam los ntim cov kua thiab qee cov khoom siv hmoov nrog cov hnab ntim khoom, feem ntau vim tias cov hnab ntim cov hnab ntim tau yooj yim dua kaw, thiab tuaj yeem rov qab siv tau, uas txo cov nqi ntim khoom thaum ua kom muaj kev noj qab haus huv thiab kev nyab xeeb. Yog li ntawd, ntau thiab ntau cov khoom tau txiav txim siab siv lub hnab ntim rau pob, yog li cov ntaub ntawv zoo li cas tuaj yeem siv los tsim cov hnab ntim khoom tuaj yeem tsuas yog ib puag ncig tus phooj ywg, tsis muaj tshuaj lom thiab tus nqi qis tau dhau los ua qhov teeb meem txhawj xeeb tshaj plaws, hauv qab no yog kev taw qhia txog dab tsi raw cov ntaub ntawv yog ua los ntawm spout hnab Qhov feem ntau tus phooj ywg environmentally!

Qhov ntom ntawm cov hnab ntim cov kua dej yog qhov tsawg: PE resins muaj ob pawg: siab ceev thiab tsawg ntom. Lub PE Molecule muaj ntau dua muaj tsawg tus ceg, thiab muaj lub zog zoo dua, tab sis lub pob tshab tsis zoo, tshwj xeeb yog cov cua sov txaus ntshai npaj los ntawm nws, lub shrinkage ntawm qhov kub thiab txias shrinkage nkhaus, qhov nqaim cheeb tsam ntawm qhov kub thiab txias insensitive cheeb tsam, thiab lub shrinkage tsis zoo, yog li thaum tsim polyethylene tshav kub shrinkable zaj duab xis, polyethylene nrog tsawg ntom yuav tsum tau xaiv (feem ntau qhov ceev yog {{ 0}}.920 ~ 0.925g / cm3 ntawm polyethylene).

Thaum cov yaj ntws nrawm nrawm qis qis, qhov hnyav molecular siab dua, thiab muaj ntau qhov sib txuam ntawm cov molecules, uas yog siv los tsim cov cua sov shrinkable nyias, thiab lub hnab ntim dej haus yog ib qho yooj yim rau kev tsim hauv zaj duab xis thiab khaws cov yuam sij. elastic deformation, uas ua rau ib tug loj shrinkage. Yog li ntawd, thaum tsim polyethylene tshav kub shrinkable zaj duab xis, nws yog zoo dua los xaiv polyethylene nrog ib tug tsawg yaj txaus tus nqi, thiab cov melt flow rate ntawm polyethylene siv nyob rau hauv tshav kub shrinkable zaj duab xis yuav tsum feem ntau tsis ntau tshaj 5g / 10min, zoo dua hauv qab 1.0 thiab 10 min.

Lub shrinkage ntawm zaj duab xis yog cuam tshuam nrog molecular hnyav faib ntawm cov resin. Feem ntau hais lus, lub tshav kub shrinkage kev ua tau zoo yog qhov zoo yog tias cov khoom hnyav molecular faib dav, yog li yog tias ua tau, nws yog qhov zoo tshaj plaws los siv bimodal polyethylene resin hauv kev tsim cov cua sov shrinkable zaj duab xis.
