Cov iav dropper fwj yog cov ntim khoom tseem ceeb hauv ntau qhov kev lag luam, suav nrog tshuaj, tshuaj pleev ib ce, thiab chaw kuaj mob. Cov fwj no tau tsim tshwj xeeb thiab ua los ntawm cov ntaub ntawv los xyuas kom meej cov kua xa tawm. Ntxiv rau lub taub hau dropper (uas tuaj yeem ua los ntawm ntau yam ntaub ntawv xws li roj hmab thiab silicone), lub khob iav lawv tus kheej tuaj yeem ua ntau yam duab thiab tuaj yeem ua tau raws li cov kev xav tau tshwj xeeb.
Part 1|Dropper Head Materials
Cov yam ntxwv roj hmab:
Zoo elasticity thiab yooj: Roj hmab dropper hau yog ib qho yooj yim rau nyem, zoo nqus thiab tso kua.
Cov tshuaj lom neeg tsis zoo: Roj hmab tuaj yeem tiv taus cov tshuaj lom neeg feem ntau, tab sis tsis haum rau cov kua qaub lossis alkalis.
Kev ua kom sov dav dav: Roj hmab feem ntau tuaj yeem tiv taus qhov kub ntawm -40℃txog 120 degree.
Daim ntaub ntawv: Feem ntau yog siv rau hauv cov chaw muag tshuaj, tshuaj pleev ib ce, thiab cov chaw soj nstuam reagents qhov twg muaj tshuaj lom neeg tsis kam thiab yooj yim ntawm kev siv.
Synthetic Rubber Yam ntxwv:
Cov tshuaj tiv thaiv zoo heev: Muab piv rau cov roj hmab ntuj, cov roj hmab hluavtaws tiv thaiv ntau yam tshuaj.
Txhim kho huab cua tiv thaiv thiab kev laus tiv thaiv: Tsim nyog rau cov khoom uas xav tau ntev - lub sij hawm durability.
Dav dav kub ntau: Feem ntau siv tau ntawm -50℃thiab 150 degree.
Daim ntaub ntawv: Siv nyob rau hauv siab -xav tau kws tshuaj thiab chaw soj nstuam droppers xav tau kev ncua ntev thiab tsis kam mus rau ntau yam tshuaj.
Silicone Rubber Yam ntxwv:
Kev ua haujlwm kub zoo heev: Silicone tuaj yeem tiv taus qhov kub ntawm 200℃lossis siab dua.
Chemical Inertness zoo: Nws tsis hnov mob nrog cov tshuaj feem ntau, ua rau nws zoo tagnrho rau kev siv siab -purity.
High Flexibility thiab Durability: Nws tuav nws yooj yooj yim txawm nyob rau hauv huab cua txias.
Daim ntawv thov: Zoo tagnrho rau siab - kub thiab siab - kev siv purity nyob rau hauv chaw ua tshuaj, tshuaj pleev ib ce, thiab chaw kuaj mob.
Neoprene Rubber (NBR) Cov yam ntxwv:
Cov Roj Zoo thiab Tshuaj Tiv Thaiv: Cov roj hmab neoprene tiv taus qee cov kuab tshuaj thiab roj av- raws li cov khoom lag luam.
Nruab nrab Thaum tshav kub kub Resistance thiab Mechanical Strength: Nws feem ntau ua hauj lwm nyob rau hauv ib tug kub ntawm -20℃mus rau 120 degree.
Huab cua zoo: Resistant oxidation thiab ozone degradation.
Daim ntaub ntawv: Haum rau cov droppers uas yuav tsum tau tiv thaiv cov roj thiab tej yam tshuaj, feem ntau siv nyob rau hauv industrial daim ntaub ntawv.
Nitrile Rubber (NBR) Cov yam ntxwv:
Cov Roj Ua Haujlwm Zoo: Nitrile roj hmab muaj zog tiv thaiv roj.
Zoo Mechanical Properties: Nws muaj lub zog thiab puas ua haujlwm.
Kev Tiv Thaiv Kev Kub Kub Nruab Nrab: Qhov ntsuas kub zoo yog -40℃txog 120 degree.
Daim ntaub ntawv: Feem ntau yog siv rau hauv cov tshuaj rau cov roj- cov khoom siv (xws li cov tshuaj pleev ib ce thiab cov roj yam tseem ceeb).
Thermoplastic Elastomer (TPE) Cov yam ntxwv:
Kev sib xyaw ua ke ntawm qhov zoo ntawm cov yas thiab cov roj hmab: TPE muaj qhov yooj yim ntawm cov roj hmab thaum tuav lub zog zoo txhua yam.
Kev yooj yim ntawm kev ua: tuaj yeem tsim los ntawm kev txhaj tshuaj molding tshuab. Cov tshuaj tiv thaiv zoo: Ua tau zoo tiv thaiv ntau yam tshuaj.
Daim ntaub ntawv: Droppers muaj ntau yam kev siv, tshwj xeeb tshaj yog rau cov khoom uas xav tau cov yam ntxwv ua tau zoo, xws li cov khoom siv tshwj xeeb lossis cov khoom tshwj xeeb.
Thaum xaiv cov khoom siv lub taub hau, nws yog ib qho tseem ceeb uas yuav tau xav txog cov hauv qab no raws li cov kev cai tshwj xeeb:
Chemical compatibility: Xyuas kom cov khoom siv dropper tuaj yeem tiv taus cov tshuaj lom neeg ntawm cov kua nws dispenses.
Qhov kub thiab txias: Xaiv cov khoom siv uas tuaj yeem tiv taus qhov kub ntawm qhov chaw uas lub dropper yuav siv.
Flexibility thiab usability: Rau kev ua haujlwm tau zoo, cov khoom siv yuav tsum yooj yim rau extrude thiab rebound sai.
Durability thiab lifespan: Xav txog cov khoom tiv thaiv kev laus thiab kev ua haujlwm ntev -. Txhua yam khoom muaj nws qhov zoo thiab tsim nyog rau kev siv tshwj xeeb.
Piv txwv li, lub siab kub tsis kam ntawm silicone roj hmab ua rau nws zoo tagnrho rau siab - qhov kub thiab txias ib puag ncig, thaum roj tsis kam ntawm nitrile roj hmab yog zoo - haum rau cov roj dispensing - raws li tshuaj. Los ntawm kev nkag siab txog cov khoom no, cov neeg tsim khoom thiab cov neeg siv tuaj yeem ua cov kev xaiv paub los txhim kho kev ua haujlwm thiab kev ua neej ntawm lawv lub raj mis dropper.
