1. Qhov tshwm sim ntawm qhov khoom neeg dag tau tshwm sim los ntawm ntau yam, xws li: ziab khaub ncaws ntawm lub hauv paus ntaub, dov ntawm cov nyom, thiab curling ntawm straw, thiab lwm yam. Cov qoob nyoos manufacturers tsis kho nyob rau hauv lub sij hawm raws li nyom fiber thiab tuft ceev ntawm lub straw. Lub qab daim ntaub ua rau cov tom qab kev tsim kho ntawm cov khoom cua dag. Raws li ntau xyoo ntawm kev tsim cov kev paub, qhov kev hloov kho ntsuas yog sau ua ke. Nws yog pom tias siv 165 g ntawm daim ntaub los ntxiv daim phiaj daim phiaj los yog ob npaug 120 g ntaub ntaub ntuab raug pom zoo kom tsis txhob thawb los yog ntes ntes ntawm qhov txuas.
2, kua nplaum txhuam hniav Qhov no tseem muaj ntau ntawm cov ntoo uas tsis yog-txheem qoob nyoos feem ntau ntsib mob taub hau, feem ntau tsis muaj qhov system, cov neeg ua haujlwm kho qhov ceev los ntawm kev ceev dhau, SBR cov dej tsis tau tag nrho faib tawm ntawm lub xov xwm, thaum qhib cov nyom Tus phenomenon ntawm thermal expansion thiab contraction tshwm sim, ua ib lub nrig npliag, ua rau cov neeg ua haujlwm paving tuaj yeem qhib riam lossis kua nplaum ua kom tsis muaj teebmeem tshwm sim, uas cuam tshuam rau tag nrho tsos ntawm cov nyom.
3. Lub winding yog ua tau ib qhov txuas nplaum. Lub winding ntawm cov khoom cua dag yog qhov kawg txuas txuas. Muaj ntau tus neeg tsav tsheb tsis nkag siab lub tswv yim ntawm qhov sib tw, thiab xav tias qhov ceev nrooj zoo. Nyob rau hauv qhov tseeb, qhov loj ntawm lub dov yog raws li qhov siab ntawm nyom. Density Nws tau txiav txim siab tias qhov no yuav siv sij hawm ntev mus vam rau qhov xav ntawm summing li hom nyom muaj ib tug ceev ceev, txwv tsis pub nws yuav muaj ib tug hesitation.
Qhov tseeb, nyom kuj yog ib txoj kev sib raug zoo, qhov curvature ntawm nyom yog qhov curvature tsis haum tib yam yuav tshwm sim, vim hais tias qhov nyom winding tsis nyob rau tib theem, tab sis yuav muaj ntsws.
