PVL daim ntawv yog cov khoom tsim los siv cov cuab yeej tshwj xeeb. Rau nws cov khoom siv, ntau yam khoom siv hlau siv: cov pa roj carbon tsawg, galvanized, tooj dag, txhuas, tooj liab, thiab tseem ua los ntawm cov hlau tsis muaj steel. Cov ntawv hlau nthuav dav tau siv dav hauv kev tsim kho niaj hnub, kev lag luam thiab kev lag luam hauv lub tebchaws.
Tam sim no, ntau qib ntawm PVL raug tsim tawm (cov ntawv tuab yog qhia hauv cov kab tuav):
- mark 406 (4mm);
- qib 506, 508, 510 (5mm);
- qib 606, 608, 610 (6 mm).
Daim ntawv thov
PVL daim ntawv yog, ua ntej ntawm tag nrho cov, cov khoom siv rau kev tsim kho. Tab sis nws cov kev ua haujlwm zoo tau nquag siv hauv kev tsim khoom thiab hauv lub neej txhua hnub. Ntawm no yog qhov ua tsis tiav ntawm daim ntawv thov rau PVL:
- khoom ntawm decks, ya davhlau ntawm ntaiv, cov kauj ruam thiab ntu rau kev tsim kho;
- kev tsim kho qhov chaw hauv ntau qhov kev lag luam;
- kev siv zog ntawm cov pob zeb muaj zog;
- tsim tawm cov grilles tiv thaiv thiab saib qhov rais hauv kev tsim kho tshuab;
- tsim cov gratings rau cua sov radiators;
- tsim kev txhawb nqacov ntsiab lus thaum thov plaster;
- kev tsim vaj tse, laj kab;
- tsim tawm ntau lub thawv;
- kev tsim kho ntawm verandas, gazebos thiab balconies;
- tsim pem teb los tiv thaiv plam pem teb;
- khoom ntawm kev cuam tshuam ntawm kev cuam tshuam ntawm txoj kev nrog kev mus los;
- cais ntau yam raw khoom rau hauv feem los ntawm sieving;
- tsim tawm ntau yam khoom dai;
- txhawb kev hla hauv cov mines thiab fais fab nroj tsuag;
- tsim khoom ntawm lwm cov qauv hlau rau ntau lub hom phiaj.
Tsev tsim khoom
PVL daim ntawv yog tsim los ntawm kev txiav ib daim hlau nrog nws cov duab ntxiv. Hom kev tsim khoom no tshem tawm cov khoom pov tseg, uas txo cov nqi ntawm cov khoom tiav. Cov thev naus laus zis niaj hnub no ua rau nws muaj peev xwm tswj tau qib txaus ntawm lub zog ntawm cov ntawv hlau nthuav dav.
Cia peb tham luv luv txhua theem ntawm kev tsim khoom.
- Theem 1. Ntawm daim ntawv hlau, siv riam tshwj xeeb, ib qho notch yog sib npaug rau hauv cov qauv checkerboard. Cov ntaub ntawv tseem ceeb ntawm kev txiav yog " nplai" thiab "rhombus".
- Theem 2. Cov ntawv xuas nrig yog ncab kom txog thaum lub hlwb yog cov duab thiab loj.
- Theem 3. Cov ntaub stretched nrog lub tiav notch yog dov ntawm tshwj xeeb shafts. Qhov no yog qhov tsim nyog kom cov ntawv hlau PVL ua kom zoo dua thiab tsis tshua muaj deformation thaum lub sijhawm ua haujlwm ntxiv. Thaum dovcov hlwb yuav tsum nyob rau hauv cov kev taw qhia ntawm kev txav ntawm daim ntawv.
Kev tsim khoom yog ua raws li kev cai tshwj xeeb (TU 36.26.11-5-89 thiab TU 27.1-25484714-001). Kev tsim cov PVL los ntawm cov hlau tsis tshua muaj hlau yog ua raws li GOST 8706-78. Yog tias dov hlau ua los ntawm tooj dag, txhuas lossis galvanized steel yog siv, ces pom GOST 380-94.
txiaj ntsig
Dab tsi yog qhov zoo ntawm cov khoom xws li nthuav cov ntawv hlau? PVL muaj ntau yam zoo. Rolling thev naus laus zis tso cai rau koj los tsim ib daim ntawv hlau uas muaj peev xwm tiv taus qhov deformation, muaj peev xwm tuav tau ib qho zoo. PVL daim ntawv muaj qhov hnyav dua li cov hlau uas tsis muaj qhov taw qhia. Ua tsaug rau cov cuab yeej no, kev teeb tsa ntawm PVL tau yooj yim heev. Lub zog zoo ntawm cov khoom txiav txim siab lub peev xwm ntawm daim ntawv kom tiv taus cov khoom hnyav thiab ua rau nws tuaj yeem txiav PVL yam tsis muaj qhov sib kis. Tsis tas li ntawd, lub xub ntiag ntawm cov ntiv taw tiv thaiv kev swb.
Tus nqi
Ntau hom dov hlau, suav nrog PVL daim ntawv, yog qhov xav tau zoo ntawm kev tsim kho kev lag luam. Nws tus nqi nyob ntawm qhov dav, uas tuaj yeem sib npaug li 50, 60, 71, 80, 90 lossis 100 cm, nrog rau cov hlau dab tsi ntawm daim ntawv. Koj tuaj yeem yuav cov khoom lag luam nthuav dav hlau 406 los ntawm 1100 rubles ib thooj. Tus nqi ntawm cov khoom no hom 508 yog los ntawm 2100 rubles ib daim ntawv. PVL ua los ntawm galvanized steel thiab txhuas yog pheej yig dua li nthuav cov hlau ua los ntawm cov hlau alloy thiab tooj liab. Tsis tas li ntawd, tus nqi nyob ntawm thaj tsam ntawm daim ntawv thiab qhov loj ntawm lub hlwb, thiab nyob rau hauv ntau yamyog sib tham.
