Laminated Veneer Lumber (LVL) ndi matabwa opangidwa mwaluso omwe amagwiritsidwa ntchito pomanga. Njira yochizira LVL ndi hydrogen sulfide (H2S) kapena haidrojeni (H2) imatha kugwira ntchito zosiyanasiyana kutengera zomwe mukufuna ndikugwiritsa ntchito. Nazi zifukwa zina zomwe LVL yaku Australia ingachitire izi:
.
Kutetezedwa ndi Kukhalitsa:
.
Chithandizo cha H2S: Mankhwala a H2S atha kugwiritsidwa ntchito ngati chosungira kuteteza nkhuni kuti zisawole, bowa, ndi tizilombo. Izi ndizofunikira makamaka ku Australia, komwe nyengo zina ndi chilengedwe zimatha kukulitsa kuwonongeka kwa nkhuni.
.
Chitetezo ku Kuwonongeka Kwachilengedwe:
.
Chithandizo cha H2S: H2S imadziwika ndi mankhwala opha bowa komanso mankhwala ophera tizilombo. Kuchiza LVL ndi H2S kumathandiza kupewa kukula kwa bowa ndikuthamangitsa tizilombo toboola nkhuni, kumapangitsa kuti matabwawo azikhala olimba.
.
Kulimbana ndi Chinyezi:
.
H2 Chithandizo: Mankhwala a H2 atha kugwiritsidwa ntchito pochepetsa kuyamwa kwa chinyezi kwa nkhuni. Izi ndizofunikira m'madera omwe ali ndi chinyezi chambiri kapena kumene nkhuni zimawonekera kuzinthu. Kukana chinyezi kumathandiza kupewa kutupa, kupindika, ndi kuwola pakapita nthawi.
Dimensional Kukhazikika:
.
Machiritso onse a H2S ndi H2 angathandize kuti LVL ikhale yokhazikika. Pochepetsa kukhudzidwa kwa nkhuni ku kusintha kwa chinyezi, mankhwalawa angathandize kusunga mawonekedwe ndi kukula kwa zinthu zomwe zimapangidwira.
.
Kutsata Miyezo:
.
Nthawi zina, kasamalidwe ka matabwa angafunike kuti akwaniritse zofunikira zamakampani kapena malamulo okhudzana ndi chilengedwe, chitetezo, kapena kulimba. Kuchiza ndi H2S kapena H2 kungakhale mbali ya ndondomekoyi kuti muwonetsetse kuti anthu akutsatiridwa.
Ndikofunikira kudziwa kuti kusankha pakati pa chithandizo cha H2S ndi H2 kungadalire zinthu zomwe zimafunidwa pazomaliza komanso zofunikira zowongolera m'derali. Kuonjezera apo, kuganizira za chilengedwe ndi thanzi ziyenera kuganiziridwa pogwiritsira ntchito mankhwala opangira nkhuni. Nthawi zonse tchulani miyezo yamakampani ndi zitsogozo za njira zoyenera zochizira ndi kuyika kwake.
