Kun min na FRP (fibreglasi reinforced plastic) sanfɛlanw bɛ se ka kɛ izini sow "so kɛnɛman" ye, o ye k’u bɛ izini koɲɛw mago jɔnjɔnw dafa cogo dafalen na, yɔrɔ yeelenba-yɔrɔ yeelenko la, fanga ni muɲuliba, ani ladonni musaka dɔgɔman. U bɛ se ka laadala sanfɛlanw dimi yɔrɔw ɲɛnabɔ ani ka izini sow baarakɛcogo ɲɛ.
1. Ka izini sow yeelenko gɛlɛya jɔnjɔnw ɲɛnabɔ
A ka c’a la, izini sow bɛ dɔn ni "span belebele ye, sanfɛla ka bon, ani baarakɛwaati jan", o min bɛ ɲinini caman kɛ yeelenko "kelenya, sabatili, ani datugucogo" kan. FRP (fibre de verre reinforced plastic) tile yeelenbɔlanw bɛ se ka o wajibiw dafa ka ɲɛ.
Yeelen jɛnsɛnnenba, min tɛ yeelen bɔ- ani fiyentɔya tɛ a la: FRP (plastique reinforced en fibre de verre) yeelen-yɔrɔ yeelenbɔlanw yeelenbɔlan bɛ 75%-85% bɔ, wa yeelen bɛ jɛnsɛn fibreglasi fɛ a jɛnsɛnnen kɔfɛ, o bɛ i yɛrɛ tanga yeelen ma min bɛ kɛ ni gilasi ye. Hali izini sow kɔnɔ minnu janya bɛ tɛmɛ mɛtɛrɛ 10 kan, yeelen bɛ se ka fɛn dilanni siraw, fɛn marayɔrɔw ani yɔrɔ wɛrɛw datugu cogo kelen na, o bɛ dɔ bɔ baarakɛcogo filiw la minnu bɛ sɔrɔ sigida yeelen dɛsɛ fɛ.
A bɛ se ka ladamu-span jɔli belebelebaw ma ni cɛsiri tɛ minnu na: FRP sanfɛlanw bɛ se ka kɛ ka kɛɲɛ ni u janya ye, wa u bɛ se ka siri ɲɔgɔn na jikuruw cogo la walasa ka se ka span dɛmɛbaliw sɔrɔ minnu bɛ se mɛtɛrɛ 30 ma walima ka tɛmɛ o kan. U tɛ i n’a fɔ gilasi, u man kan ka tila tilayɔrɔ misɛnninw na walasa ka sigi, o bɛ yeelen tiɲɛniw dɔgɔya minnu bɛ sɔrɔ jirisunw sirili fɛ, o b’a to u bɛnnen don kɛrɛnkɛrɛnnenya la yɔrɔba-sow jɔli ma i n’a fɔ nɛgɛso iziniw ani fɛnw ladonyɔrɔw.
Yeelen jiginni sabatilen kuntaalajan ani a dɔgɔyali hakɛ dɔgɔyali san tan kɔnɔ : Sanfɛla plastiki gansanw yeelen bɔli bɛna dɔgɔya ni 30% ye san 3-5 kɔnɔ, k’a sɔrɔ FRP sanfɛlanw, ka tɛmɛn sanfɛla anti-UV datugulan fɛ, olu bɛ se ka yeelen bɔli dɔgɔyali hakɛ kɔlɔsi ka se 2% ma san kɔnɔ walima min bɛ bɛn 2% ma san kɔnɔ. Ni u bɛ baara kɛ cogo la min bɛ kɛ cogo la san 15 kɔnɔ, u bɛ se ka yeelen bɔli sabati hali bi min ka ca ni 60% ye, o bɛ kɛ sababu ye ka pannew caman cili kɛ tuma caman na izini sow kɔnɔ k’a sababu kɛ yeelen dɛsɛ ye.
2. Ka izini sigida ka "hardcore" kɔrɔbɔli muɲu
Tuma caman na, izini sow bɛ sigida gɛlɛnw sɔrɔ i n’a fɔ gaziw minnu bɛ fɛnw tiɲɛ, fɛn girinmanw bɛ ɲɔgɔn gosi, ani waati juguw. FRP (fibreglasi reinforced plastic) sanfɛlanw farikolo cogoya bɛ se ka o gɛlɛyaw ɲɛnabɔ k’a ɲɛsin u yɛrɛ ma, ka dɔ bɔ lakana faratiw la ani u ladonni musakaw la.
Nɔgɔ-min bɛ se ka sɔgɔ ani asidi ni alkali-min bɛ se ka kɛlɛ, a bɛnnen don atelier kɛrɛnkɛrɛnnenw ma: Kemikɛli, kuran, pickling ani baarakɛyɔrɔ wɛrɛw bɛ se ka asidi ni alkali gaziw bɔ. Glass gansan bɛ sɔgɔ nɔgɔya la ani ka nɔgɔ, ka sɔrɔ FRP yeelen translucent panneaux bɛ se ka dilan ni vinyl ester resin ye, o bɛ asidi ni alkali kunbɛncogo ɲɛ ni siɲɛ 3-5 ye. Ni a kɛra waati jan kɔnɔ, a yɔrɔ tɛna bugun walima ka a lamini, wa a mago tɛ ka nɔgɔ bɔ tuma bɛɛ walima ka a falen.
A bɛ se ka wuli kosɛbɛ, a tɛ siran tiɲɛni ɲɛ kasaara la: A ka c’a la, izini iziniw bɛ baara kɛ i n’a fɔ forokili minɛcogo ani masin kɔrɔtacogo. FRP sanfɛlanw ka bɔgɔbɔgɔli bɛ se ka kɛ gilasi ta siɲɛ 2-3 ye. Hali ni fɛn girinmanw ye a gosi walima ni sanbɛlɛ ye a sɔrɔ, a bɛna a yɛrɛ tiɲɛ sigida la dɔrɔn sanni a ka kari, o bɛ kɛ sababu ye ka minɛnw tiɲɛni walima mɔgɔ jogin min bɛ sɔrɔ gilasi karilen fɛ.
Weelecogo min bɛ se ka ladamu waati kɛrɛnkɛrɛnnenw na: A kɛra nɛnɛba ye min bɛ se degere -30 ma wo, a kɛra fiɲɛba ye wo, FRP sanfɛlanw bɛ se ka baara sabatili sabati. A funteni dɔgɔyalen bɔgɔbɔgɔli funteni bɛ Dɔgɔya walima a bɛ bɛn -40℃ma , wa a fiɲɛbɔ doni tali bɛ se ka se 2,5kPa ma, o b’a to a bɛnnen don izini sow ma waati cogoya danfaralenw na i n’a fɔ kɔgɔjida yɔrɔw ani dugukolojalanw.
3. Ka dɔ bɔ izini sow ka ɲɛnamaya musaka bɛɛ lajɛlen na.
Industri sow bɛ " musaka-nafa sɔrɔli" ani "baarakɛcogo ɲuman" bila jɔyɔrɔ fɔlɔ la. FRP (fibreglasi reinforced plastic) sanfɛlanw bɛ se ka musakaw dɔgɔya kosɛbɛ k’a ta u sigili fɔlɔ la ka se u ladonni kɔfɛ, ka bɛn ni izini porozɛw musaka kɔlɔsili hakilina ye.
Ni u sigili ka nɔgɔn, o bɛ kɛ sababu ye ka jɔli ni baarakɛlaw musakaw bɔ : FRP sanfɛlanw girinya bɛ se gilasi tilancɛ dɔrɔn ma, o bɛ kɛ sababu ye ka nɛgɛ girinmanw ni kranw mago bɔ i n’a fɔ gilasi sigili. Panɛli kelen bɛ se ka lamaga mɔgɔ 2-3 fɛ, wa sanfɛlan mɛtɛrɛ kɛrɛnkɛrɛnnen 10000 sigili waati bɛ se ka surunya ka se tile 3-5 ma, o bɛ dɔ fara a sigili nafa kan ni 50% ye ni i y’a suma ni gilasi ye, o bɛ dɔ bɔ baarakɛlaw ni minɛnw jago musakaw la k’a ɲɛsin u yɛrɛ ma.
Ladonni dɔgɔyali ani fɛn si man kan ka bila a nɔ na, o bɛ dɔ bɔ baarakɛbaliya waatiw la: FRP (plastique reinforced en fibre de verre) sanfɛlanw bɛ se ka kɛ cogo la min bɛ kɛ cogo la san 15-25 kɔnɔ k’a sɔrɔ u ma wuli, o bɛ kɛ sababu ye ka san o san sanfɛla buguri saniya nɔgɔman dɔrɔn de wajibiya. Ni an y’a suma ni plastiki panɛri gansanw ye minnu ka kan ka wuli san 3-5 o san 3-5, o bɛ kɛ sababu ye ka baarakɛbaliya bɔnɛw bali iziniw ka fɛn dilanni siraw la, k’a sababu kɛ sanfɛlanw cili ye, o min nafa ka bon kosɛbɛ kɛrɛnkɛrɛnnenya la, iziniw bolo minnu ka fɛn dilanni taabolo bɛ taa ɲɛ i n’a fɔ kemikɛli ni mobili dilanni.
Kuwati dɔgɔyali ani a tacogo dɔgɔyali, waatijan-marani baara musakaw la : FRP sanfɛlanw ka funteni-bɔn hakɛ (0,18W/(m・K)) ka dɔgɔ kosɛbɛ ka tɛmɛ gilasi ta kan (0,76W/(m・K)), o bɛ se ka dɔ bɔ funteni dalajɛli la izini kɔnɔ samiyɛ fɛ ani ka fiɲɛbɔlan doni dɔgɔya ni 15%-20% ye o waati kelen na, yeelenbɔcogo caman bɛ se ka kɛ yeelen dilannen 40%-60% nɔ na. Ka da izini kan min janya ye milimɛtɛrɛ 10000 ye, a bɛ se ka kuran musaka 80.000-120.000 ɲɔgɔn bɔ san kɔnɔ.
