Mapulogalamu
DB-235 Yoyenera utoto wamatabwa, ndi zina zotero. Ili ndi tinthu tofanana, imafalikira mosavuta, imawoneka bwino, komanso imagwira ntchito bwino popewa zala ndi zotsalira za zala. Ikagwiritsidwa ntchito mu utoto wamatabwa wa matt 2K PU wokhala ndi ufa wa silica matting, utotowo ukhoza kukhala ndi mawonekedwe ofewa, umatha kukhala ndi mphamvu yolimba komanso umakana kukanda. Imakhalanso ndi mphamvu yolimbana ndi kukhazikika kuti isagwere mu ufa wa silica matting. Ikagwiritsidwa ntchito ndi silica, chiŵerengero cha polyethylene wax micropowder ndi ufa wa matting nthawi zambiri chimakhala pafupifupi 1: 1-1: 4.
Ili ndi kukana kukalamba komanso kusalala bwino, ndipo ingagwiritsidwe ntchito ngati zophimba za ufa zomwe zimagwira ntchito ngati kuzimiririka, kutsetsereka, kuuma, kukana kukanda komanso kukana kukangana.
Kulimba bwino, malo osungunuka kwambiri, kungathandize kwambiri pakukana kukanda komanso kukana kumatira m'njira zosiyanasiyana.

Mlingo
Mu machitidwe osiyanasiyana, kuchuluka kwa ufa wa sera wowonjezera nthawi zambiri kumakhala pakati pa 0.5 ndi 3%.
Kawirikawiri imatha kufalikira mwachindunji mu zophimba ndi inki zopangidwa ndi zosungunulira pogwiritsa ntchito kusakaniza kwachangu.
Kudzera mu makina osiyanasiyana opera ndi chipangizo chobalalitsira chapamwamba, chogwiritsidwa ntchito popera, chiyenera kutsatiridwa ndi kulamulira kutentha.
Mukhoza kupanga pulp ya sera ndi sera pa 20-30%, ikani mu makina ngati pakufunika, zomwe zingathandize kuti nthawi yobalalitsa sera isungidwe.

Phukusi ndi Kusungirako
1. Chikwama cha 20KG
2. Sungani mankhwalawa pamalo ozizira, ouma, komanso opumira bwino kutali ndi zinthu zosagwirizana.
