Ua li no, xaiv ib daim ntaub nrog ib ntu ntawm 42 g / m2 sup2 lossis 60 g / m2 sup2. Nyob rau hauv lub caij ntuj sov, lub spunbond tiv thaiv tawm tsam cua, ua noo noo. Nyob rau hauv lub caij nplooj ntoos zeeg, nws yuav pab kom txuag tau cov txiv hmab txiv ntoo ntawm cov txiv hmab txiv ntoo los ntawm kab npoo thaum ntxov. Nyob rau hauv lub caij ntuj no, npog cov qoob loo, tiv thaiv lawv los ntawm cov snow cover. Nws kuj yog siv rau txaj thiab mulching.
Hom spunbond
Qhov nrov tshaj plaws yog spunbond 42, tus yam ntxwv ntawm cov uas ua ke coincide nrog cov saum toj no. Nws yog ib qho khoom noj khoom haus uas kis tau lub hnub lub hnub, tab sis tiv thaiv cov nroj tsuag ntawm ultraviolet hluav taws xob. Nws loj yog 2.1 x 10 m.
Lwm hom toj kab yog spunbond 60. Cov yam ntxwv tseem muaj cov lus qhia zoo xwb. Nws muaj nyob hauv dawb los sis dub. Qhov chaw ntawm daim ntawv thov - kev tiv thaiv ntawm cov nroj tsuag nyob rau hauv loj heev frosts, rub on ib thav duab tsev xog paj.
Paub txog cov yam ntxwv ntawm cov spunbond, koj tuaj yeem thov nws raws li qhov zoo tshaj plaws.
