Resin pobzeb yog ib hom ntawm cov nplais hluavtaws uas ua rau muaj kev cuam tshuam thiab su, uas peb tsis txhob'
Cov laj thawj tseem ceeb ntawm kev txiav txim siab tsis ncaj thiab tawg ntawm cov nplais hluavtaws muaj raws li nram no:
1. Daim phiaj lossis plaub qhov puag ncig ntawm cov nplais hluavtaws tsis sib npaug.
2. Qhov zoo ntawm cov khoom siv hluavtaws yas tsis zoo. Yog tias cov khoom siv rov ua dua tshiab cov khoom raug cambered arbitrarily, lub camber tsis sib xws.
3. Cov dej ntsiab lus ntawm cov nplais hluavtaws tawv yog qhov loj thiab qhov tsis zoo yog qhov tsis tsim nyog, ua rau shrinkage deformation.
4. Kev teeb tsa ntawm purlins lossis qhov sib nrug ntawm purlins yog qhov loj heev, uas ua rau tsis kho tsis meej tom qab keel deformation.
5. Cov neeg kho tshuab sib xyaw ua ke ntawm cov nplais ntawm cov nplais tsis tau txuas nrog nruj, uas ua rau kev hloov chaw thiab deformation.
6. Cov ntsiab lus tshwj xeeb ntawm cov nplais hluavtaws xob yog ntau heev, tshwj xeeb tshaj yog npog cov xim pobzeb steel. Qhov kub nthuav dav thiab txias ua kom sib piv ntawm ob cov ntaub ntawv sib txawv, thiab nyias cov nplais hluavtaws cov nplais yog yooj yim npuas.
Txij li thaum peb nkag siab cov laj thawj tsis sib xws ntawm cov khoom siv hluavtaws tawv, peb yuav tsum tswj hwm nws, thiab siv kev tiv thaiv rau cov kev ua kom muaj qhov tsis sib xws, uas tuaj yeem tiv thaiv los ntawm cov hauv qab no.
1. Cov nplais ntawm cov nplais hluavtaws yuav tsum tau ua los ntawm cov phaj, thiab cov cuab yeej tsim tawm ntawm cov khoom cua cob hluavtaws yuav tsum
2. Cov nplais ua hluavtaws tawv yuav tsum yog 3. Hli 0 kom deb li sai tau, thiab qhov sib nrug ntawm purlin yuav tsum txog 660 m.
3. Tus keel yuav tsum ncaj thiab ncaj, thiab yuav tsum tsis txhob twisted lossis muaj lub hauv paus ntawm transverse los ntawm ntu. Cov txheej txheem npaj ua hluavtaws tawv yog txhua yam ua los ntawm cov khoom siv tshiab thiab nruj me ntsis ua raws cov txheej txheem ntau lawm.
4. Kev teeb tsa ua los ntawm cov nplais hluavtaws yuav tsum yog sib txig sib luag ntawm cov kab nyob ib puag ncig raws cov qauv tsim qauv. Thaum ntsia ntsia hlau, qhov chaw ib puag ncig yuav raug rau kab tav toj. Qhov siab ntawm txoj kab ntawm kab rov tav yog 1 / 200 ntawm lub chav luv, thiab lub plooj ntev yuav tsum tau txhaws qhov muag.
