Phazi lagalasi (dzina loyambirira mu Chingerezi: galasi fiber kapena fiberglass) ndi mankhwala osavomerezeka. Imakhala ndi zabwino zambiri. Ubwino ndi wabwino kwambiri, kukana kwamphamvu kwamphamvu, kukana kokoma kokongola, komanso kulimba kwambiri, koma zovuta zake zimakhala zopanda pake, zosauka. Phazi lagalasi nthawi zambiri limagwiritsidwa ntchito ngati zinthu zolimbitsa thupi m'magawo ophatikizika, zida zamagetsi zotupa ndi zotupa zamagetsi, matabwa ozungulira ndi minda ina yazachuma.

Kodi cholinga chachikulu cha fiberglass?
Mafuta a galasi ulusi umagwiritsidwa ntchito ngati zotchinga zamagetsi, zosefera za mafakitale, zonyoza, zotupa, zimatha kugwiritsidwanso ntchito ngati zinthu zolimbitsa thupi. Kugwiritsa ntchito ulusi wa galasi kufinya kwambiri kuposa mitundu ina ya ulusi kuti akhazikike kwambiri pulasitiki, ulusi wagalasi ulusi kapena zolimbitsa rabani, simenti yolimbikitsidwa, zinthu zina zolimbikitsidwa. Magalasi fiber yarn imayatsidwa ndi zinthu zachilengedwe kuti zizisinthasintha ndikusinthana nsalu, kuwunika pazenera, kuphimba nsalu, kuphimba nsalu, komanso zovala zotchinga. Ndi kutchinjiriza ndi zida zokopa.

Kodi mungasiyanitse bwanji kuti mukuyenda bwino?  
Phazi lagalasi limapangidwa ndigalasi ngati zopangira komanso zomwe zimakonzedwa ndi njira zosiyanasiyana zokuurira mu dziko losungunula. Nthawi zambiri amagawanika mu chitsamba chagalasi komanso chiberekero chagalasi. Pamsika, ulusi wopitilira magalasi umagwiritsidwa ntchito. Pali zinthu ziwiri zazikulu zatsamba wopitilira. M'modzi ndi chiberekero chagalasi-alkali, dzina lolemba C; Wina ndi alkali-free galasi, code-dzina la E. Kusiyana kwakukulu pakati pawo ndi zomwe zili zachitsulo za alkali. Mbewu yagalasi yapakatikati-alkali ndi (12 ± 0,5)%, ndi alkali-free galasi fiber ndi <0.5%. Palinso zogulitsa zagalasi yopanda tanthauzo pamsika. Wodziwika bwino ngati ulusi wamphamvu wa alkali. Zomwe zili ndi zitsulo za alkali zitsulo zili pamwamba pa 14%. Zida zopangira zopanga zimasweka galasi lathyathyathya kapena mabotolo agalasi. Mtundu wamtundu wa galasi uli ndi madzi osakanizika, mphamvu yotsika yamagetsi ndi makulidwe amagetsi, omwe saloledwa kupangidwa ndi malamulo adziko.

Zogulitsa zambiri za alkali ndi alkali ndi alkali ziyenera kukhala zoumba kwambiri pa bobbin pa bobbin, ndipo ma bobin aliyense amalembedwa ndi nambala yake, nambala yovuta ndi kalasi, ndipo chitsimikizo chowunikira chimayenera kuchitika mu bokosi lonyamula. Zomwe zimapezeka ndi kuwunika kwa malonda ndi chitsimikiziro chikuphatikiza:
1. Dzina la wopanga;
2. Code ndi kalasi ya malonda;
3. Chiwerengero cha muyezowu;
4. Sitampu yokhala ndi chidindo chapadera cha kuyendera;
5. Kulemera kwa ukonde;
6. Bokosi la matsambalo liyenera kukhala ndi dzina la fakitale, nambala yazogulitsa ndi kalasi, nambala yokhazikika, kulemera kwa mat, ndi nambala ya batch, etc.
