Kub Sov Shrink Tubing

Cov cua kub ntsws los yog lub cua sov ua kom sov (shrinkable plastic tube) siv cov hlua khi, muab kev thev tawm thiab kev tiv thaiv ib puag ncig rau kev sib txuas thiab cov hlau xaim hluav taws xob, sib txuas, cov pob yas qij thiab cov khoom siv hauv hluav taws xob . Nws kuj siv tau los kho lub rwb thaiv tsev ntawm lub xov tooj los yog kom nrig lawv ua ke, los tiv thaiv xaim hluav taws xob los yog qhov chaw me me los ntawm kev txhim kho me , thiab tsim kev ruaj ntseg thaiv cov ntaub thaiv kab, muab kev tiv thaiv ib puag ncig. Kub-shrink tubing yog ordinarily ua los ntawm nylon los yog polyolefin , uas shrinks radially (tab sis tsis ntev itudinally) thaum rhuab, mus rau ntawm ib nrab thiab ib-sixth ntawm nws txoj kab uas hla.

Kub-shrink tubing yog manufactured nyob rau hauv ib tug tibneeg ntau ntau yam thiab cov tshuaj pleev ua rau muaj pes tsawg tus yam ntxwv ntawm txhua hom ua nyob rau ntawm daim ntawv thov. Los ntawm kab ze phab ntsa ntawm phab ntsa ua kom nruj, hnyav-phab ntsa tubing, txhua hom muaj cov qauv tsim thiab cov tshuaj siv tshuaj uas ua rau nws tuaj yeem ntsib ib qho ntawm ntau qhov kev xav tau. Heat-shrink tubing yog muab los ntawm nws txoj kev nthuav dav, kev sib piv ntawm qhov sib txawv ntawm kev nce thiab rov ua haujlwm.

SIV:

Cov hlua khib nyiab yog siv rau ntawm cov hlau ua ntej ua qhov kev sib txuas, ces yoojyim los npog qhov sib koom ua ke tom qab nws tau ua. Yog hais tias qhov haum nruj, kua roj nplua nyeem yuav tsum muaj ntaub ntawv tsis muaj kev cuam tshuam rau cov khoom kub-ntsws.Qhov tub yuav muab qhwv kom nruj nrawm ncig lub qhov cub los ntawm qhov cub lossis kub cua los yog lwm qhov chaw ntawm cov roj kub. Yooj yim tab sis tsis tshua zoo sib xws rau kev thawb lub raj muaj xws li ib cov kav hlau uas tuav ze ze tab sis tsis kov lub raj, los yog kub ntawm ib qho sib zog . Tshav kub tsis tshee muaj peev xwm ua rau tsis sib haum, lub cev ua kom tsis muaj zog thiab cov khoom thaiv tsis raug, thiab cov tswv yim no tsis raug pom zoo los ntawm cov neeg siv khoom hauv heatshrink.Yog hais tias overheated, kub-shrink tubing tuaj yeem tawg, ua kom kub nyhiab lossis kub hnyiab zoo li lwm yam yas. Cov cua kub ua rau tubing rau daim ntawv cog lus rau nruab nrab ntawm ib nrab thiab ib nrab ntawm nws thawj kab, nyob ntawm cov ntaub ntawv siv, muab ib txoj hlua haum zoo dua cov pob txha tsis sib xyaw. Muaj qee qhov ntev, qhov tsis txaus siab thiab qis dua li qis qis dua, feem ntau ntawm 6% .Tshooj tub hluav taws muaj hluav taws xob zoo , tiv thaiv plua plav, cov xuab zeb thiab lwm yam khoom siv txawv teb chaws, (tshwj tsis yog lub npog loj heev los yog tsis ntuag) los ntawm nws ceev nrooj.

Ib co hom kub-ntsws muaj ib txheej ntawm thermoplastic   nplaum sab hauv los pab muab txoj kev ruaj ntseg zoo thiab zoo dua adhesion, thaum lwm tus neeg vam khom ntawm kev sib cov khoom sib ze. Qhov cua sov uas tsis yog siv hluav taws xob los ntswg los mus ze ntawm qhov chaw melting tej zaum yuav cia nws mus fuse rau lwm yam khoom zoo li [ qhov yuav tsum tau ].

Heatshrink tubing yog qee zaum muag nyob rau hauv qhov kev txiav ua ntej txiav, nrog rau lub voj tshuab ntawm lub qhov ntev ntawm qhov ntev, vim hais tias daim qauv no yog daim ntawm Daimler-Benz rau kev kho tsheb hluav taws xob.

Ib daim ntawv thov uas tau siv heatshrink rau ntau qhov txij thaum 1970s yog daim ntaub npog ntsej muag ntawm cov khoom siv fiberglass antennas , siv ntau rau 27 MHz CB xov tooj cua . Muaj ntau plhom tus tswv ntawm cov antennas tau coated li no.

Cov kev siv ntau yam yuav tsum muaj cov ntaub ntawv sib txawv:

Elastomeric leeg tuav lub zog yooj yooj yim txawm tias tsis tshua muaj kev kub thiab sib zog ua raws cov qauv thoob ntiaj teb. Lawv kub cov haujlwm kub kub -75 mus txog 150 ° C. Cov khoom siv tiv thaiv rau ntau yam chemicals (xws li lub roj thiab roj) thiab muaj kev tiv thaiv zoo rau kev puas tsuaj , txawm nyob hauv tej qhov xwm txheej loj heev. Ib qho piv txwv yog 2: 1.

Fluorinated ethylene propylene (FEP) yog tus nqi qis dua rau cov PTFE. Nws yog lub tshuab hluav taws xob ntau yam thiab nws yog tshuaj rau cov tshuaj feem ntau thiab cov tshuaj solvent. Tsis tas li ntawd, nws yog ib qho uas tiv taus huab cua kub, txias, thiab Ultraviolet hluav taws xob, ua rau nws siv khoom zoo heev rau cov cua sov thim tube daim ntaub ntawv.

Polyolefin plawv, hom tshaj plaws, muaj qhov siab tshaj plaws-uas siv tau los ntawm qhov -55 txog 135 ° C, thiab siv los ntawm cov tub rog, kev davhlau thiab kev lag luam. Lawv yooj yooj yim thiab ceev nrawm, thiab manufactured hauv ntau hom xim (xws li meej), uas yuav siv tau rau cov xim xaim xim. Nrog rau kev zam ntawm dub, lawv yuav muaj qis tsis kam mus rau ultraviolet lub teeb; raws li, tsuas yog dub yog pom zoo rau cov ntaub ntawv rau sab nraum zoov. Polyolefin tubing shrinks ntawm 143 ° C.Polyolefin kub-shrink tubing feem ntau shrinks 2: 1 diametrically, tab sis qib high-grade polyolefin kub-shrink tseem muaj nrog 3: 1 piv.Polyolefin tubing tej zaum yuav tau mus kov nrog ib cov kav hlau.

PVC tubes muaj nyob rau hauv ntau xim thiab tuaj yeem siv sab nraum zoov. [Qhov yuav tsum tau muaj ] PVC kub-shrink nyhav yog tias kov ib tus kav hlau.

Polyvinylidene fluoride (PVDF) plab roj hmab yog tsim rau cov kev kub ntxhov siab.

Silicone rubber muaj kev xyuam xim rau kev txhuam thiab txav ceev. Nws cov haujlwm kub thiab txias yog -50 rau 200 ° C [ qhov yuav tsum tau muaj ]

PTFE (fluoropolymer) plab muaj qhov kub thiab txias (-55 txog 175 ° C), muaj qhov tsis sib haum ntawm kev sib txhuam , thiab muaj kev tiv thaiv rau cov tshuaj thiab punctures.

Viton , lwm fluoropolymer nrog tshuaj lom neeg muaj peev xwm, yog dav siv nyob rau hauv cov khoom siv hydraulic. Nws yog ib qho yooj yim heev, nrog rau kev khiav hauj lwm kub ntau ntawm -55 rau 220 ° C, ua rau nws haum rau kev tiv thaiv kev tiv thaiv siv hluav taws xob.

Lwm cov ntaub ntawv tshwj xeeb muaj nyob rau hauv, muab cov khoom zoo xws li kev ua haujlwm rau lub cav ntoo thiab cov hlua fais fab, thiab tseem muaj ntaub qhwv ntaub, muab kev txhawj xeeb ntau hauv cov cheeb tsam hnyav.

Hom:

Kub-shrink tubing yog muaj ntau yam xim rau xim-coding ntawm xov hlau thiab sib txuas. Thaum pib nees nkaum-thawj xyoo thaum tshav kub kub-pib tub luam pib siv rau PC modding kom huv si li ntawm sab hauv ntawm cov computers thiab muab ib qho tsos xav pleasing [ citation ntxiv ]. Hauv kev teb rau txoj kev qhib kev ua lag luam no , cov lag luam pib tsim cov cua kub ntsws hauv cov luminous thiab UV reactive ntau yam.

Txawm hais tias feem ntau yog siv los thaiv, kev kub-shrink tubing nrog ib txoj hlua hluav taws xob kuj tseem muaj, rau kev siv cov pob qij txha uas tsis tuaj yeem siv .

Cov cua kub-thawv tubing, lub npe hu ua "tsho tes tsho", muaj ib lub raj hauv sab hauv lub tshav kub-ntswg, qhov hluav taws xob los mus txuas rau ob lub xov hlau los ntawm melting lub kauj ruam thiab ib txhij thev thaiv cov hlws ris nrog lub tubing. Cov tsho muaj plhaws feem ntau kuj muaj lub nplhaib ntawm cov cua kub-tshuab cim rau hauv sab hauv ntawm txhua tus raj ntawm lub raj, cia qhov kev sib txuas mus los ua dej tsis tau.

Thaum tshav kub kub-ntsws kawg lub kaus mom, kaw ntawm ib kawg, raug siv los thim qhov raug txiav qhov xaus ntawm cov hlua hluav taws xob. (Sau los ntawm Wikipedia)
