Thaum nws los txog rau kev ntim khoom thiab kev thauj mus los, thawj qhov uas ntau tus neeg xav txog yog siv "lub hnab ntim khoom" los tuav cov khoom. Nws yog cov khoom siv yas ntau heev tam sim no thiab tau siv dav hauv kev lag luam vim nws muaj ntau cov ntaub ntawv thiab yog cov kabmob load. Nws muaj kev ua tau zoo thiab yooj yim dua thaum thauj mus los, ua rau kev thauj mus los ntawm cov khoom siv ntau yam yooj yim heev. Txawm li cas los xij, nws muaj ntau heev rau cov hnab ntim khoom tawg, yog li lub sijhawm no, peb yuav tsum tau kho nws sai sai ua ntej nws tuaj yeem muab tso rau hauv ib txwm siv. Yog li puas muaj cov lus qhia rau kev kho sai?
Ua ntej tshaj plaws, kev tsim cov thawv ntim khoom:
Base fabrics feem ntau yog tsim los ntawm cov looms tiaj tus lossis shuttle ncig looms. Rings, slings, thiab knots feem ntau ua tiav los ntawm looms. Kev xaws xov tuaj yeem siv xov nylon, xov polypropylene, polyester xov, los yog paj rwb xov. Nws yuav tsum muaj cov coefficient ntawm ntau tshaj 5 zaug, uas yog, nws lub siab tsis kam yuav tsum tiv taus tsib npaug ntawm lub zog ntawm qhov hnyav. Yuav tsum muaj dej-pov thawj muaj nuj nqi thaum tsim nyog.
Thib ob, txoj kev xaws ntawm lub hnab ntim khoom:
Muaj peb txoj kev xaws rau cov hnab ntim khoom: tiaj tiaj, txoj kev sib tshuam, thiab txoj kev sib tshooj. Nws tuaj yeem raug kho raws li cov neeg siv khoom xav tau thiab tsim los siv ntau txoj kev xaws. Cov no yog cov thev naus laus zis tsim nyog rau kev tsim cov thawv ntim khoom kom ntseeg tau tias cov thawv ntim khoom tsim tau zoo.
Piv txwv li: qhov rupture point ntawm lub thawv ntim khoom yog qhov kov ntawm lub thawv ntim khoom. Nyob rau lub sijhawm no, nws yuav tsum tau muab sau tseg tias qhov no yog qhov chaw muaj kev ntxhov siab thiab qhov chaw uas muaj kab nrib pleb tshwm sim. Nws muaj ob txoj hauv kev los kho nws sai. Ib qho yog txiav qhov tawg ntawm qhov qub tawg. Txiav nws tawm, thiab tom qab ntawd siv lub tshuab xaws los kho nws nrog ob txoj xov. Qhov kev ncua deb ntawm ob txoj hlua yuav tsum tsawg dua 10MM.
Lwm qhov yog siv ib tuj lub hnab thaj ntawm cov khoom qub los kho thaj chaw tawg, nrog rau lub tshuab ob kab ncaj nraim, thiab qhov kev ncua deb ntawm sab nrauv suture thiab periphery ntawm daim ntaub thaj tsis pub tsawg tshaj 20MM. Yog tias lub hnab ntim khoom puas rau sab lossis hauv qab, nws tsuas yog kho tau lub sijhawm no siv lub tshuab xaws lossis lub tsheb tiaj tus. Lub pob tw foob yog 3 koob thiab 5 xov. Nyob rau lub sijhawm no, nws yuav tsum tau muab sau tseg tias qhov loj ntawm thaj yuav tsum loj dua qhov loj ntawm qhov kev puas tsuaj, thiab qhov tsawg kawg nkaus yuav tsum tsis pub tsawg tshaj 20MM. Yog tias kev ua haujlwm hnyav hnyav, nws raug nquahu kom kho cov txheej txheem sab hauv thiab sab nrauv kom lub hnab kho tuj yuav muaj zog dua.
