Foam ea polyurethane e fafalitsoeng (SPF) e hapile tlhokomelo e kholo indastering ea meaho le ea ho kenya lintho kahare e le tharollo ea ho kenya lintho kahare e bolokang matla le e tšoarellang. Ebang ke ts'ebeliso ea bolulo, khoebo kapa indasteri, ho kenya lintho kahare ho foam e fafalitsoeng ho tsebahala haholo ka ts'ebetso ea eona ea mocheso, ho se kene moea le ho boloka litšenyehelo tsa nako e telele. Empa na ho kenya kahare ho foam e fafalitsoeng ke mohopolo o motle? A re hlahlobeng potso ena ho tsoa ponong ea moetsi oa li-catalyst tsa polyurethane, re tsepamisitse maikutlo saenseng e ka morao ho SPF le karolo ea bohlokoa eo li-catalyst tsa polyurethane li e bapalang ho etsoe ha tsona.
Ho Sireletsa Foam ka Spray ke eng?
Ho thibela ho bola ha foam e fafatswang ho etswa ka ho kopanya metsoako e mmedi e meholo ya mokelikeli: isocyanate le polyol, hammoho le di-catalyst, di-surfactant, di-law retardants le di-blowing agents. Hang ha e fafatswa, motswako o atoloha ka potlako ho etsa foam e tiileng, e kwalehileng kapa e bulehileng ya sele e tlatsang dikgeo, mapetso le masoba, e fanang ka ho thibela ho bola ha mocheso le mokoallo wa moya.
Ho na le mefuta e 'meli e meholo ea ho thibela foam ea spray:
- Foam e fafatsang ka lisele tse bulehileng: e bobebe, e na le boima bo tlase, 'me e na le thepa e monyang molumo.
- Foam e Koetsoeng ea Spray ea Sele: E na le boima bo phahameng, e fana ka mokoallo oa mouoane le boleng bo holimo ba R ka intshi.
Hobaneng ha Spray Foam e le Khopolo e Molemo
1. Tshebetso e Phahameng ea Thermal
SPF e fana ka e 'ngoe ea boleng bo holimo ka ho fetisisa ba R ka lisenthimithara ha e bapisoa le ho kenya mocheso oa setso. Sena se etsa hore e be e loketseng mehaho moo sebaka se fokolang empa ho hlokahala tšebeliso e ntle ea matla.
2. Thibelo ea Moea le Mongobo
Foam e fafatswang e etsa sekwahelo se tiileng se fokotsang ho dutla ha moya, ho kena ha mongobo le ho ntsha moya o kenang ka hare. Sena se thusa ho thibela kgolo ya hlobo le ho ntlafatsa boleng ba moya ka tlung.
3. Matla a Sebopeho
Foam ea Spray ea Sele e Koetsoeng e ka eketsa botšepehi ba sebopeho sa mabota le marulelo, e leng se etsang hore e be e loketseng libaka tse nang le sefefo se matla kapa meea e matla.
4. Bophelo bo Bolelele le ho Boloka Litšenyehelo
Foam e fafalitsoeng e kentsoeng hantle e ka nka lilemo tse fetang 20 ntle le ho thekesela kapa ho lula fatše. Litšenyehelo tsa pele hangata li fokotsoa ke poloko ea matla ea nako e telele le tšebeliso e fokotsehileng ea HVAC.
Karolo eaLi-Catalyst tsa Polyurethaneho Spray Foam Insulation
Li-catalyst tsa polyurethane ke metsoako ea bohlokoa mefuteng ea foam ea spray. Li laola sekhahla sa karabelo lipakeng tsa isocyanate le polyols, li susumetsa lintlha tse latelang tsa bohlokoa:
- Lebelo la ho ntsha moholi (karabelo ea ho ntsha moholi)
- Lebelo la pholiso (karabelo ea gel)
- Profaele e se nang tack le e phahameng
- Sebopeho sa sele ea foam le boleng ba bokaholimo
Khamphani ea rona e ikhethile ka ho khetheha ka amine e sebetsang hantle leli-catalyst tsa tšepeE etselitsoe litsamaiso tsa SPF. Li-catalyst tsa rona, tse kang MXC-T, MXC-37, MXC-C15 le MXC-R40, li fana ka likarolo tse latelang:
- Mesi e fokolang le monko o fokolang
- Tieho e leka-lekaneng ea karolo e ka pele le phekolo ea karolo e ka morao
- E lumellana le li-agent tsa ho letsa tsa HFO
- Ho khomarela ha matla ho substrates
- Taolo e ntle ea ho phahama ha foam le pheko ea bokaholimo
Ka ho ntlafatsa khetho ea li-catalyst, bahlahisi ba ka iketsetsa litsamaiso tsa foam ho fihlela litlhoko tsa lits'ebetso tse fapaneng tsa foam ea spray, joalo ka ho thibela lebota, marulelo, polokelo e batang le ho thibela liphaephe.
Likopo tsa ho Sireletsa Foam ka Spray ho Sebelisa Li-Catalyst tsa Rona
Li-catalyst tsa rona tsa polyurethane li sebelisoa lits'ebetsong tse fapaneng tsa SPF, ho kenyeletsoa:
- Ho Sireletsa Matlo (Likamore tse ka tlas'a lefatše, Mabota, Likamore tse ka tlas'a lefatše)
- Meaho ea Khoebo le ea Liindasteri
- Matlo a polokelo a sehatsetsing le Likamore tse batang
- Ho kenya Tanka le Phaephe ka Sehatsetsing
- Mekhoa ea Marulelo le Liphanele tsa Sandwich
Re sebetsa haufi-ufi le baetsi ba liforomo le lik'hamphani tsa sistimi ho fana ka litharollo tsa li-catalyst tse ikhethileng tse netefatsang ts'ebetso, polokeho le ho latela maemo a tikoloho.
Qetello: Na Spray Foam ke Khopolo e Molemo?
Ka 'nete - ho thibela foam ea spray ke letsete le bohlale la nako e telele le ntlafatsang ts'ebetso ea matla le boiketlo. Leha ho le joalo, katleho ea eona e itšetlehile haholo ka k'hemistri e nepahetseng ka mor'a foam. Jwalo ka moetsi oa litsebi oa li-catalyst tsa polyurethane, re utloisisa saense ea SPF 'me re ikemiselitse ho thusa balekane ba rona ho hlahisa litsamaiso tsa foam tse sebetsang hantle, tse nang le mosi o fokolang.
Haeba u moetsi oa foam ea spray kapa formulator ea sistimi u batla litharollo tsa catalyst tse sebetsang hantle haholo, tse se nang monko o motle, le tse sa senyeheng tikolohong, re u mema hore u hlahlobe pokello ea rona ea lihlahisoa kapa u ikopanye le sehlopha sa rona sa botekgeniki bakeng sa puisano.
