Tsim kev Silicone Tubing

Saj zawg zog elastomers yeej tseem ceeb heev rau txoj kev loj hlob ntawm cov tshiab thiab txoj kev kho mob, kev sealing, gasketing, thiab dej hloov zog lwm yam ntaub ntawv feem coob tsis tau. Silicone elastomers particular ua muaj ntaus ib tug loj nyob rau hauv cov ntaub ntawv kev feem ntawm teg num no. Thaum uas siv cov inputs feem coob yuav tsis mob allergenic teb, thiab tsis txhob qhia rau sawv daws kuj plasticizers, silicone elastomers muaj kuj tau muab chaw feeb ntau txais kev pab los ntawm kev txo nqi khoom xws li cov PVC thiab cov yas latex.

Silicone tubing no mas siv nyob rau hauv daim ntaub ntawv xws li kuj, drains, pub leeg, thiab peristaltic tej twj uas lom compatibility yog ib tug tseem ceeb yuav tsum tau. Manufacturers xav silicone rau cov ntawv xaiv kawm qib uas raws li stringent huv chaw ua hauj lwm raws, xws li kawm VI ntawm USP thiab ISO 10993.

Cov silicone tubing siv nyob rau hauv txoj kev tu mob lag luam yog tsev uas siv ib txoj kev nruam extrusion nrog kub cua vulcanizing ncu los kho qhov tubing thermally. Raws li cov tau tab sis, yog los ntawm cov hlab ntsha zoo heev rau kev phais kho qhov muag rau txoj kab uas hla 3-in. tubing rau hose tshuab muaj muaj zog tso. Ntxiv rau cov pa tubing, ntau designs uas muaj ntaub los yog hlau qhov cuab lub zog yog tau as well as tej lumen tubing muaj ntau cov thauj khej li qhov qub siv.

Tsis zoo li thermoplastics xws li PVC, uas yog tiav raws cua kub rau ib tug yaj rau tom txias kom daim ntawv tiav, silicones cov khoom thermoset uas yog sib crosslinked thiab thiaj li yuav muaj deformation ntau tawm. Feeb ntau, ntau extruded silicone roj hmab tubing no vulcanized siv organic peroxide tua tau kab mob. Tiam sis, platinum tua lub nruab kuj nrov vim lawv siab purity zus thiab tsis extractables, vim muaj ntau txaus kho "by-products."

Thaum seem tolerances rau thickness ID thiab phab ntsa rau extruded tubing yuav hais mus li ntawm ob peb thousandths ntawm ib nti, cyclical variation puas yuav tau nrog ib tug txheej txheem nruam extrusion.Kua puab txhaj siliconeelastomers muaj ib lwm txoj kev ua zoo, qhov tsis kim heev dhau thiab muaj tsis ntev los no tau muab siv kom muaj silicone roj hmab raj rau uas peristaltic-ru cartridges siv enteral noj. Elastomers silicone kua muaj ob-tivthaiv, platinum kho, pumpable silicones uas tau muab puab thiab kho kom sov uas siv txhaj-molding cov cav tov uas cov ntaub ntawv qhia thermoset. In contrast to extrusion, molding pub rau ib txoj kev ntsuas thiab exacting qhov ntev uas ua rau neeg tus me nyuam paub twj tso kua mis. Tswj lub raj ntsuas zoo yuav pab kom muaj tswv yim tshiab twj designs tsiv paub thiab kev ua tau zoo yav tom ntej siv dej. Vim li ntawd, ua kua silicone elastomers muab tubing manufacturers nrog kev xaiv ntxiv rau hauv ntau daim ntaub ntawv tubing yav tom ntej.
