now that im used to trainings, i injured myself again.
:/ it will recover.
i dun mind waiting for you until late becos i wanna see you longer.
i dun mind all though bastard stuff cos that shows how close we are.
but how long ca this last? we are so close because of these consecutive trainings. but what will happen when school reopens? same GEMs however different class. why do i feel the fear of loosing you?

PROPERTIES OF GLASS
MECHANICAL PROPERTIES
-brittle
-completely elastic to its ultimate tensile strength
-will fail at low stress due to presence of microscopic surface cracks
OPTICAL PROPERTIES
-transparent
-can be treated in different ways to reflect and absorb different degree of light
-tinted glass absorb more light than clear
-reflective coated glass reflects large portion of glass depending on the nature of coat , colour and thickness
THERMAL PROPERTIES
-solar gain through glass heats up inside of building
-cause running cost for aircons and heat loads
-different types of glass implemented such as insulating glass, reflective glass and tinted glass.
TYPES OPF NON-SAFETY GLASS
CLEAR SHEET GLASS
-used for normal glazing
-relative good quality with low cost
-smooth, hard finish and scratch resistant
-lack of superior quality of plate and float glasses
-lower quality sheet glass made by drawing upwards molten glass, a thin sheet
-cooled, rising sheet solidifies, then cut
-both surface less parallel
-lower quality of float glass
PLATE GLASS
-grounded and polished after drawn from furnace
-glass then pass through grinding unit
-polished smooth and parallel before cut
FLOAT GLASS
-has nearly optically true surfaced that is fire polished
-interchangable with plate glass for most application
-plate and float glass is stronger
-use in higher quality situations
-eg. showcase
SAFETY GLASS
TEMPERED GLASS
-heating regualr annealed glass almost until melting point and chilled rapidly
-thin skin of glass produced at both sides
-under high compression, places centre of glass in high tension
-tempered glass 3-5 times stronger
-breakable
-thin outer skin is pierced, glass shatters
-into small pebble like pieces
-safer than original glass
-must be cut before tempering
LAMINATED GLASS
-2 or more sheets of class stucked together with polyvinyl butral plastic between them
-binded under heat and pressure
-when broken, glass will adhere into plastic inter-layer without evacuating
-minimise cutting injury and hazards
-entrance door , interior partitions
WIRED GLASS
-metal wire mesh placed into centre of glass thickness during manufacturing
-glass pieces cling to wire when broken
-minimise flying of glass and injuries
-remain in one place even though cracked by excessive heat
SPECIAL GLASS FOR SPECIFIC PURPOSES
PATTERNED GLASS
-obscured optical properties
-insert patterns to glass
-allow differnt degrees of light transmission
-large range of patterns
-privacy use
-privacy use
-should be tempered for safety
INSULATED GLASS
-factory produced
-air tight unit consist of 2 layers of glass with a dehydrated air space in between
-protect window areas
-reduce heat loss in winter and heat gain in summer
-used in residental and commercial buildings
TINTED GLASS
-reduce soloar heat
-cut down glare
-to provide useful atmosphere
-grey and bronze tint
-windows, sliding glass doors, lirabries
REFLECTIVE COAT GLASS
-coated with thin layer of metallic-films
-reflect sunray
-reduce solar heat
-reduce aircon system cost
-grey, blue silver gold bronze
GLASS BLOCKS
-manufactured in two seperated halves
-heat sealed to form hollow unit
-with good thermal efficiency and sound insulation
-functional and directional
-functional: to diffuse/direct light that passes through them
-illuminates interior of building
-decorative: ability to control an overall design plan
-not intended to use as major control of daylight

2.LEVEL LOOP
-stitches of yarns
-like a hooked rug with equal height loops
-crucial performance
3. CUT AND LOOP
-plush and loop pile
-varnishes in pile height
-shearing of yarns caused unusual effects
-used in many areas
-not for formal setting
4. SAXONY
-plush look alike surface
-twisted in the yarns for durability
-gives wool like luster
-for luxury, top performance
5.VELVET PLUSH
-plush finish with yarn twisted
-breaks smooth surface lush aka tailored plush
-luxury objective
6.BERBER
-loop pile runs in parallel lines
-rugged surface gives wool like appearance
-durable, stain resistant
-hides dirt, footprints and other tracks
-some constructed in multilevel loops
-create patterns and other effect
-available in most carpet fibres
-available in cut pile
-luxurious feeling of thick pile carpeting
MANUFACTURING OF CARPET
1.TUFTED
-machine method
-inserting large loops or stitches to backing material
-liquid latex added after that
-to firmly lock loops
-height of loops adjustable for requirements
-knife used in conjunction with loops to create cut pile carpet
-fastest way
-most economic way
-cheaper than woven carpet
2.WOVEN
-popular method
-interlacing filling yarns
-with warp yarns
-different techniques gives different appearance
-weaving techniques: wilton, axminster, velvet
3.NEEDLE PUNCHING
-punching pile fibres
-into loosely woven carrier fabric
-using barbed needle
-made with pre-dyed polypropylene
-in smooth flat surface
-backed with latex or latex foam
-available in tiles

events experience class. .
doing nothing and i found my blog dead as a log.
BORED! i twisted my knee i cannot train i wonder if i can play on wednesday..
seniors criticise and demoralise ppl, however some encouraged.
projects cramped up, presentation on friday. need to mug with hsihwa later, tml nees to get stuff n gv cip record to fuck face, onow presentation tml. THIS IS TIRING. ok im hungry now. where am i going to eat? hmm FC2? with cheap food! but so CROWDED!!!! nvm. save money for my CROCS! ARG first pair just came and i cannot wear! PEK CHECK CAN! ok i wana eat. wooohoo~

when they talked about it, i hoped nthn was true.
however it turned out this way that everything was so true.
i can lie, but, i know the truth, so no point.
it always happens, i seemed to be strong, but somehow so weak.
feeling so bitter and sour inside, now, more empty.
confessions of a broken heart.
im gona be okay, it just takes time.
ITS GONA HEAL FAST.

cmcc so darn bond la!!
the two survivor freshie tagged along with seniors go clementi eat.
den they game we play arcade!
addicted to jubox! omg!
hahhas!! spdb! training today!
looking foward!
