Kodi Velcro kapena friction splint ndi chiyani?

Tayala la friction kapena "Velcro" ndi gulu la matayala achisanu omwe amatha kumamatira pamwamba pa ayezi popanda kuyika zitsulo. Ngati mu mphira wodzaza ndi kuyanjana kwa zokutira zoterera ndi kupondapo kumakhala ndi kukangana kwa mphira ndi kumamatira kwa ma studs, ndiye kuti mumkangano umodzi wokhawo umagwiritsidwa ntchito.

Kugwira kwa gudumu ndi msewu makamaka kumadalira ma checkers a njira yopondapo. Kuchuluka kwa chiwerengero chawo komanso kutalika kwa m'mphepete mwa chigamba cholumikizira, gudumu lidzagwira bwino msewu wachisanu. Pa mathamangitsidwe, m'mphepete kumbuyo kwa chipika chipika adamulowetsa, pamene braking - kutsogolo.

Makhalidwe ndi mfundo za mphira wokangana

Zomwe zimagwira ntchito za Velcro zimapereka mawonekedwe apadera a mphira ndi mawonekedwe a pamwamba pa tayala:

• lamellas ambiri;
• kufewa kwa zipangizo;
• porous kapangidwe;
• abrasive microparticles.

Matayala onse akukangana amalumikizidwa ndi kuchuluka kwa sipes. Lamella ndi kachingwe kakang'ono ka mphira komwe kumagawanikapo. Kupatukana uku kumawonjezera kukakamiza kwa zokutira, potero kukwaniritsa kumamatira bwino. Pali mitundu iyi ya lamellas:

• chopingasa;
• diagonal
• zigzag.

Woteteza Velcro ali ndi zingwe, monga wodzitchinjiriza wina aliyense. Kusiyanitsa kuli pakuchulukirachulukira kwa makonzedwe, komwe kumakhudza bwino mtunda, kulola kugwiritsa ntchito kuchuluka kwa lamellas. Ndi m'mphepete mwa sipes kuti matayala amamatira pamwamba, ndipo kuphatikiza ndi kuponda kwakukulu, chigamba chokhazikika komanso chachikulu cholumikizira chimapangidwa.

Pansi pa kulemera kwa galimotoyo, lamellas muzitsulo zopondapo zimasiyana, zomwe zimamatira pamwamba pa msewu wotsekedwa ndi chipale chofewa. Pochoka pamalo olumikizirana ndi msewu, ma sipes amalumikizana, ndikudzitsuka matayala, ndikuchotsa tchipisi ta ayezi ndi matalala.

Koma lamellas ali kutali ndi chikhalidwe chofunikira chokha. Ziribe kanthu kuti ndi angati omwe amaperekedwa, kugwiritsira ntchito kwambiri kumangotha ​​kutsimikiziridwa ndi mapangidwe a porous a rabara. Ndi iye amene angamwe madzi akamagunda mseu.

Rabara ya Velcro imakhala ndi chosakaniza cha cryosilane ndi silika, kotero sichimatentha pa kutentha kochepa, ndipo ma micropores ambiri amakhetsa filimu yamadzi. Pamlingo wa mamolekyu, pore iliyonse ya tayala imalumikizana ndi msewu molingana ndi mfundo ya chikhomo choyamwa, chomwe sichimangogwira ntchito yogwira bwino, komanso mtunda waufupi wothamanga. Panthawi imodzimodziyo, opanga ambiri amalengeza kuwonjezera kwa ma microparticles olimba a organic ndi organic chiyambi kusakaniza mphira. Ma abrasives oterowo amagwira ntchito ngati ma mini-spikes, omwe amangowonjezera mikangano.

Kodi pali kusiyana kotani pakati pa mphira wabwinobwino ndi friction?

Kumene kulibe ayezi ndi chipale chofewa, njira yabwino ndiyo kugwiritsa ntchito mphira wothamanga. Ndi mikhalidwe iyi yokhala ndi matalala otayirira, phala la matalala ndi phula lonyowa zomwe zimakhala m'misewu yamizinda yaku Ukraine m'nyengo yozizira. Matayala a friction amathanso kugwiritsidwa ntchito pakatentha kwambiri masana, ndipo chisanu chimatha usiku ndipo sikuthekanso kugwiritsa ntchito matayala achilimwe.

Matayalawa amakhala ndi mphira wofewa kuposa matayala ophimbidwa ndipo amatentha pang'ono pakazizira kwambiri. Kuthekera kwawo kuti agwire modalirika pamtunda wamsewu kumasungidwa kutentha kwa minus 25 ° C ndi pansi.

Matayala a friction alibe spikes. Choncho, mmodzi wa ubwino kuposa mphira wophimbidwa mwachiwonekere - amakhala opanda phokoso. Pa chipale chofewa, palibe kusiyana kulikonse, koma pa ayezi kapena phula, matayala akukangana amakhala opanda phokoso. 

Matayala ophunzirira kunja kwa mpikisano pa ayezi woyera ndi matalala odzaza. Ma spikes ndi othandiza makamaka pamalo oterera potentha pafupi ndi kuzizira pamene pali madzi oundana pamwamba pa ayezi kuti akhale ngati mafuta. Matayala ophwanyika m’mikhalidwe yoteroyo sagwira ntchito. Ma studs adzayamikiridwa ndi madalaivala osadziwa. Koma ma spikes ndi aphokoso kwambiri, osayenerera kuyendetsa mothamanga kwambiri, amakhala ndi mtunda wotalikirapo wa braking panjira yonyowa ndikuwononga kwambiri msewu. M'mayiko ambiri ku Ulaya, ntchito yawo ndi yochepa kapena yoletsedwa kwathunthu.

Matayala amwaka wonse sali konse "tanthauzo la golide", monga momwe zingawonekere poyang'ana koyamba, chifukwa ndi otsika pakuchita kwawo kwa matayala achilimwe ndi achisanu. Izi sizili kanthu koma kunyengerera poyesa kuphatikiza zotsutsana. Oyendetsa magalimoto ku Europe amagwiritsa ntchito matayala oterowo makamaka munyengo yakutali.

M'mikhalidwe ya Ukraine ndi oyandikana nawo kumpoto, matayala a nyengo yonse alibe chidwi. Kutentha kwa ntchito yabwinoko ndi yopapatiza - kuchokera ku chisanu pang'ono mpaka + 10 ° C. Panthawi imodzimodziyo, kugwira kodalirika ndi msewu wamtunda kumatheka pokhapokha pamtunda wokhazikika komanso wowuma. Kuyendetsa pa chipale chofewa ndi ayezi pamatayala oterowo ndikowopsa. Sizingatheke kusunga ndalama pogula seti imodzi kwa nyengo zonse, koma chitetezo kapena, osachepera, chitonthozo choyendetsa galimoto chidzakhala pachiwopsezo.
