Ukukhetha okubanzi kwezindlela zomdlalo wehlathi

Apr 17, 2025

Ukuphatha kwezinto zomphakathi we-UL standard wooden fireproof doors (UL certified) kufuneka zikhuse izicwangciso zokugcwalisa amaxhego (UL 10C/UL 10B), ukusetyenziswa, ukubuyilelwa ngokulandelana nendawo (EPA/LEED), kunye neziqondiso. Ngenqaku lwe-NFPA 80 kunye ne-ASTM E84, ukuphatha kwezinto zomphakathi zewudi inxuvesi yamakhono apha ekukhethweni lokuhlola umoya wemoto, ukuphuma amandla okuhlola umoya wemoto kunye nokuhlinza isimo sokushesha kwiindlela yokumela.

Umthetho Wokusebenzisa Kwesayithi

1. Ukuphathiswa Kwesayithi

Ukukhetha Amadi:

Iphutha elisodwa (njenge-oak, imfene) noma i-plywood yomoya omkhulu (ezikhathalayo kwi-ANSI/HPVA HP-1 standard) iyaphakamiswa.

Ukuphakama kwemoto ukuqhelekelayo kufuneka kulandelwe phakathi kwe-8% kunye ne-12% (ukuvikela ukusuka nokungabhedekelanga).

Ukuphatha komoya (iphase le nto):

Umsebenzi wokuhlola ngokubheka lokugcino

Ubutho bomoya omkhulu: I-Ammonium phosphate, i-borate noma i-amino resin type (ezikhathalayo kwi-ASTM E84 Class A).

Umvambo wokuphucula kwi-5mm okanye lapho (ukusurela uhlazo lwendawo yokugcina eliphakathi).

Ukusebenzisa isibhedlela sesiqephu esikhakhuleni (ukungabala ukufakelwa kwezintsha).

Ngemva kokuthathela, kufuneka libe lizame ukuthi i-test yokuqinisekiswa nge-temperature nenoma yezityalo (ukungavalelise ukubhukuda ngomusho).

Umbalulo wesithoba

Intsholo yesithoba sokugcina

Iphakathi lethi liphakamiswa ngu-0.5 kwi-1.2mm (uma kubheke kungenzi lokugcina umoya phakathi kwezindlela).

Ubungabadwa bubeleka ngumoya wokuqala we-5 kwe-10 uma kuhlaziywa ngephoyiso, ubhale amandla yocansi olunceda (ubunikezelwe ngokuthi UL 10C test).

Umbalaselo wesintshontshi

Ukusetshenziswa ukufaka amaphatho emibhobho yenxalenye nokuvumela umkhuhlane wophawu (ingxenye yokuhlaziywa kufuneka ikhawuleze ekuseni lwesicoco sentsha).

3. Uphawu lomkhuhlane

Ilamendi yepheni lehlukile (HPL)

Ukuphakamiswa kwi-0.8-1.5mm. Ingqambo yokugcwalisa okubanzi kunye nokusasaza (ipass UL 72 test).

Izicatshululo zokusebenza: izikhali ezidingekayo ngaphandle lokuncedisi, njengemithi nezikole.

Isivu sentshe + umphathiso wokugcwalisa

Ukuphakamiswa kwe-sivu ngu-0.6 ku-1.0mm, kunye nesibhedlela somphathiso womphofu esisityenziselweni.

I-topcoat yiya ku-sebenzisa i-penti eziqondisiweyo ezintathu lomoya olunyeleyo (VOC < 100g/L, ukubonisa amandla ze-EPA).

Ukuphuma ngokweseto lokulula umoya

Kusetyenziswa nge-indlu yesayithi, inikezwa nge-penti lokulula umoya olunyeleyo / olungaphakathi (okuthile yomthimbu).

Izicwangciso zokusebenza zokugcinwa

Isibini somoya wokuvala:

Ukwenza isicelo sokuqinisekiswa kwezandla zokuphuma elinyeleyo lweUL 10C (amagreyde ezi-20/45/90 imini).

Ubungakanani bezililo ngemva kobubanzi (ASTM E662) uyakhiwo ≤450, kunye nokuthi umthentho wakufuneka nge NFPA 286.

Ukufumanekisa ukugcina impahla yomphindo

I-flame retardant ayikho uformalide nazo zonke izimetalu ezikhulu (ukungenisa TSCA Title VI).

Ulwazi oluhluweyo kwe-VOC kukuya ku-250g/L (EPA 40 CFR Part 59).

Ukuphakamisa kwezinto ezifisanesi

Ukutesta ukugcwaliswa kweheat omncane (ASTM D4585) : Ayikho amabhabha ngemihla engu-500.

Ukucatshwa kwe-abrasion (Taber Abrasion) ≥500 amakhicelo (HPL finish).

Iv. Ukuphatha kwesiqephu nokuthetha

Ukutesta ukuphumelela kwe-flame retardant: Bheka izisele zasampuli nokukhiqiza imigomo yesilinganiso.

Ukugcwalisa kwezilondolozi zokuphuma elizenzekelayo: Umthetho wesicatshulwa sasekuqaleni (ASTM D3359) ≥4B igreydi.

Ngemvume yokuvavanya kokuphuma, uhlaziyo lwakhe ishicilele: akukho ukungabuyiselwa kunye nokuba umphathiso wokuncediswa wawufunyenwe.

V. Ukufundza nokuhlanuzela

Xesha lokusebenzisa, sebenzisa umsebenzi omncane ongaphakathi (pH 6~8) ukusureka ukungenziweyo yomphathiso.

Sebenzisa ngokwengezi lezantsi zokusebenzisa ukusureka ukuba azibuyeke ngaphandle (izigaphe zedabu edolobheni ayenza uphumeleyo wokuvaqasha).

Umbiko wokugqibela kwiqhutywa elilimi lenye kufuneka lihlale ngokuphawuliwe ngephawu lendlu yobuxoki obungaxhaswa ukuvumelanisa uphawu.

Vi. Isicatshulwa

Ukuthatha kwezinsiza zomphakathi kweedora eThekwini ezikhoyo zikufuneka zisisekelwe ngokubhekisisa amandla akwesithathu, uzihlabelela nokuhlala kunye nokusindiswa kokusebenza. Ukukhetha kwesiphumo kufuneka sikubheke ngokuba yindlela yokusetyenziswa (njengamakhaya ekhombisweni, iindlela zokusebenza noma ukuhlanganiswa okungaphambili), futhi kufanele kubhedele umthetho we-UL, NFPA kunye ne-ASTM ukusure ukuthi usizo lwesibopho lwamathathu lususiwe ngenqanawe.
